## Zombie Maths 4: Simultaneous Equations

December 13, 2011### We know the Zombie walking speed = 0.6 m/sec or 2.3 kph, rounding off.

### We know Zombie hand speed = 5 m/sec or 18 kph

### Kid walking speed is about 5 kph

### That is 5000 m

### in 60 x 60 = 3600 sec

### or , rounding off, 1.4 m/sec

.

## ……………………….y = k t

.

## ……………………….y = distance km

.

## ……………………….k = speed kph

.

## ……………………….t = time hr

# Will a Zombie catch you?

# Will a Zombie Arm catch you?

### Look at the speeds. A Zombie cannot catch you … no problem.

### BUT

### The Zombie Hand is faster than you. If it started 5km away from you, how long would it take to catch you?

### We will write two equations.

### Zombie hand Equation :

## y = 18 t – 5 ………… Eqn 1

### NB: The Zombie Hand starts 5 km away from you.

### The kid equation:

## y = 5 t ………………. Eqn 2

# How far did you walk?

### y = 5 t

### y = 5 x 0.38

### y = 1.9 km

# ZOMBIE GOT ME!!!

# ARRRRRRGGGGHHHH!

# More cool zombie stuff @

# The Laughing Mathematician.
