Question

A car travels 2 (5/8) miles 3 (1/2) minutes at a constant speed. How far did the car travel in 5 minutes?

Answer 1

3.74 miles

Explanation:

Given that,

Distance,
`d=2(5)/(8)\ \text{miles}=(21)/(8)\ \text{miles}`

Time,
`t=3(1)/(2)\ \min=(7)/(2)\ \min`

We need to find how much the car will travel in 5 minutes.

`(21)/(8)\ miles = (7)/(2)\ min\\\\1\ min= (21* 2)/(8* 7)\\\\=0.75\ \text{miles}\\\\\text{In 5 minutes}, d = 0.75* 5\\\\=3.75\ \text{miles}`

Hence, the car will cover 3.74 miles in 5 minutes.
