Question

Explain why a student who runs 3/4 mile in 6 minutes is faster than a student who runs 1/2 mile in 5 minutes?

Answer 1

The student who runs 3/4 mile in 6 minutes is faster than a student who runs 1/2 mile in 5 minutes, because his speed is greater

Explanation:

we know that

The speed is equal to divide the distance by the time

Let

s ------> the speed

step 1

Find the speed of the student who runs 3/4 mile in 6 minutes

`s=((3/4))/(6)= 0.125(mi)/(min)`

step 2

Find the speed of the student who runs 1/2 mile in 5 minutes

`s=((1/2))/(5)= 0.10(mi)/(min)`

step 3

Compare the speed

`0.125 > 0.10`

therefore

The student who runs 3/4 mile in 6 minutes is faster than a student who runs 1/2 mile in 5 minutes, because his speed is greater
