Question

A car travels at a speed of 85 miles per hour how far will it travel in 15 minutes

Answer 1

15 minutes is 1/4 part of an hour. So the distance travelled is equal to 1/4 × 85 which is equal to 21.25 miles

Answer 2

Distance travel by a car in 15 minutes is 21.25 miles

Given:

Distance travel by a car in 60 minutes = 85 miles

To find:

Distance travel by a car in 15 minutes

Solution:

We Know that,

1 hour = 60 minutes.

Given that,

Distance travel by a car in 60 minutes = 85 miles

Therefore Distance travel by a car in 1 minute $=\frac{85}{60}miles$

and  

So, Distance travel by a car in 15 minutes $=\left(\frac{85}{60}\right) \times 15 \text { miles }=21.25$

Hence,m

Distance travel by a car in 15 minutes = 21.25 miles
