Answer:

a) 20 m/s

b) No

Step-by-step explanation:

a)

Mr. G needs to run x= 200 m in t = 10 seconds to catch the bus.

Knowing the speed is computed as


\displaystyle v=(x)/(t)

We have


\displaystyle v=(200m)/(10s)=20m/s

b)

The fastest human can run 12 m/s, so Mr. G won't be able to catch the bus because he needs to run faster than that
