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!
