Question

An athlete can run long distances at 4 metres per second. How far can she run in 50 seconds? What about in 1 hour?

Answer 1

distance= velocity x time 1 = 450 = 200 m
distance= velocity x time 2 = 43600 = 14400 m= 14.4 km

Explanation:

Data of the problem

velocity= `4 m/s`
time 1= `50 s`

?=how far can she run (= it simply means find the distance)
distance= velocity x time 1 = 4*50 = 200 m

Data of the problem

velocity= `4 m/s`
time 2= `1 h`
?=how far can she run (= it simply means find the distance)
This part is a little tricky, because you need to convert hours to seconds first.

`1 h= 60 min= 60*60 s = 3600s`

distance= velocity x time 2 = 4*3600 = 14400 m= 14.4 km
