Zombie Maths 9: Length

How long for Zombie to walk around the earth?

According to The Universe Today the circumference of the earth is 40,075 km or 24,901km.

In other words, if you could drive your car around the equator of the Earth (yes, even over the oceans), you’d put on an extra 40,075 km on the odometer. It would take you almost 17 days driving at 100 km/hour, 24 hours a day to complete that journey.

As Zombie can walk under water, how long would it take Zombie to walk around the earth?

Assuming he doesn’t have to stop and that the ocean is not too deep ….

y = k t

y= 40,075 km

k = 2.25 kph

40,075 = 2.25 t

t = 40,075/ 2.25

t = 17,811  hours

t = 17,811/24  days

t = 742 days

t = 742/365

t = 2 years 12 days

ARE WE THERE YET?

…………………………Argh! Grrrr! Gurgle!
