BEAR STATISTICS
Weight: 550 lb
Height: 8’ 2”
Top Speed: 35 mph = 51 ft/s
Weight: 1,500 lb
Height: 8’ 2”
Top Speed: 22 mph = 32 ft/s
Comparing these speeds to the fastest man on earth, Usain Bolt:
Usain Bolt:
Top speed: 27 mph = 40 ft/s
Bears are not dangerous:
………………………………………………………………………
In fact, more Americans die each year from choking on their own vomit than are killed by bears.
More death stats here.
Nevertheless, bears are very fast. So you can see why Park Rangers offer the following advice:
More information at Mountain Nature.
The reason for waiting until the bear is 15 ft away is to make sure the spray doesn’t disperse in the air. If the Pepper Spray is too spread out it will not stop the bear.

METRIC UNITS below. USA UNITS here.
BEAR STATISTICS
Grizzly Bear
Weight: 250kg
Height: 250cm
Top Speed: 56kph = 16 m/sec
More bear stats here.
Brown Bear
Weight: 680kg
Height: 250cm
Top Speed: 35kph = 10m/s
More bear stats here.
Comparing these speeds to the fastest man on earth, Usain Bolt:
Usain Bolt:
Top speed: 243kph = 12m/s
So Usain Bolt could out run a Brown Bear but NOT a Grizzly!
Bears are NOT as dangerous as:
In fact more Americans die choking on their own vomit each year than a re killed by bears.
More death stats here.
But bears are very fast so Park Rangers recommend the following survival tactics:

Kilauea erupts in Hawaii MAY 2018.
The amazing maths of volcano eruptions.
Once lava flows are established new RIVERLETS can run on top of the original lava flow at great speed.
The fastest Lava flows recorded were in Hawaii in 1950 when Mauna Loa erupted. The lava traveled at 6 miles (10 kilometers) per hour through thick forest. But once the lava flows became established and good channels developed, the lava in the channels was flowing at up to 60 miles/hour (97 kph)
Can you out run a lava flow?
You are 2 km from the volcano rim and start running.
VL = 97 kph = 1.6 km per minute (k/min)
= 60 mph
VH = 18 kph = 0.3 km/min
= 11.2 mph (miles per hr )
GRAPH:
How long will it take for the lava to catch you?

Statistics for alcohol consumption are tricky. Binge drinking gets confused with heavy drinking. If you want to stay young go to the UK. They think anyone under 35 is a youth! Some stats separate Male and Female drinking habits. Some don’t. And legal drinking ages vary. Canada is one crazy place. It has different legal drinking ages in different parts of the country.
Legal Drinking Age:
The Maths
What we are working on here is reading maths data. No lectures. The numbers speak for themselves. 
Graph source here
The Challenge
Find the following information from data below. Percentage of Year 12 students or 18 year olds who binge drink in each country below.
1. Australia
Graph Source here.
2. Canada
Graph Source here.
3. UK
Graph Source here
4. USA

Use these % to create a bar graph comparing countries. (Answer below)
Graph drawn using Create a Graph website
Alcohol related death stats over lap other stats including death involving cars, motorcycles, bicycles, skateboards, jet skis, quad bikes, drowning, diving, stairs, supermarket trolleys and even high heels.

Alcohol Related Youth Death Statistics
UK1: 314
Australia2: 260
Canada3: 3,500
USA4: 4,358
- 15-34 years for 2011. Source
- 15-24 years average 1990-2002 Source
- Under 18 years of age. 1996 It is believed that as many as 83 percent of teenagers in Canada consume alcohol. Back in 1996, underage drinking was responsible for 3,500 deaths and 2,000,000 injuries. A 2002 survey found that 20 percent of eight graders had consumed alcohol within the previous month. Source
- 4,358 people under age 21 die each year from alcohol-related car crashes, homicides, suicides, alcohol poisoning, and other injuries such as falls, burns, and drowning. Source
These countries have different populations (See post below). USA population is 15 times Australia’s. 260 x 15 = 3,900. So the Aussie and US stats are in the same ball park even though the stats have been collected for different age ranges. But look at Canada. The USA population is about 9 times Canada’s. 4,358 ÷ 9 = 484 deaths. This death statistic for Canada is 10 times larger than the USA statistic per head of population. Meanwhile, the population of Canada is 1 1/2 or 1.5 times Australia’s. 260 x 1.5 = 390. Once again, the Canadian statistic is out by a factor of 10. What’s going on here?
The Bar Where You’re Too Afraid to Get Smashed
Mathspig is a party pig. But why does anyone drink themselves senseless? Many reasons, but one is they’re bored. Now here is a bar in Mathspig’s home town, Melbourne, where you better stay sober. 
Break out of prison in Trapt Bar. You’re in prison, you’re innocent, and no one believes you. You plot an escape with the other prisoners–because unless you break free soon, you’ll all face an unspeakable death (this prison is off the charts). At Trapt Bar and Escape Rooms, you and your teammates have 45 minutes to find clues, solve puzzles and escape before…well…let’s spare you the gruesome details.
