Question

Casi drove 135 miles in 3 hours. Use a proportion to find how long it would take her to drive 360 miles at the same speed.

Answer 1

8 hours

Explanation:

We are given that

Casi traveled distance in 3 hours=135 miles

We have to find the time taken by Casi to drive 360 miles at the same speed using proportion .

Let time taken by Casi to drive 360 miles=x

We know that

Speed=
`(Distance)/(time)`

Using proportion

`(a)/(b)=(c)/(d)`

`(135)/(3)=(36)/(x)`

`x=(360* 3)/(135)`

`x=8`

Hence, the time taken by Casi to drive 360 miles=8 hours
