A car travels for 2 hours 15 minutes at an average speed of 64 mph. Calculate the distance travelled.

231.746 km

Step-by-step explanation:

In order to find the answer to this question we will have to answer it using what the question gives us.

The car traveled for 2 hours and 15 minutes

The average speed of the car was 64 mph (miles per hour)

2 hours = 64 + 64 = 128

15 minutes is 1/4 of a hour which means you need to divide miles per hour by 4

64 ÷ 4 = 16 or 16+16+16+16 = 64

128 + 16 = 144 distance total

Since the answer needs to be in kilometers we need to convert miles into kilometers.

We know that..

1 mile = 1.60934 km

Which means you need to multiply 1.60934 by 144 (total number of miles) to find your answer in kilometers.

1.60934 × 144 =231.746km

= 231.746km

Hope this helps.
