Question

Team infinite dimensions canoed 15 3/4 miles in 3 hours. what was their average rate of speed in miles per hour?

Answer 1

Average speed = total distance/total time

15 3/4 / 3 = 63/4 / 3 = 63/12 = 5.25

so, their average speed was 5.25 miles/hour

Answer 2

5.25 or 5 1/4 mph.

Explanation:

Let us recall that,

The Average speed = The total time/total distance covered

Team infinite dimensions is canoed 15 3/4 Miles

The Hours from the example =3

So,

15 3/4 / 3 = 63/4 / 3

which is 63/12 = 5.25

or in another way, we can also arrive at the same solution which is,

15 3/4=15.75

15.75 miles/3 hours=5.25 or 5 1/4 mph.

the average speed in miles per hour is, 5.25 miles/hour
