Question

Team tool bella canoed 15 3/4 miles in 5/4 hours. What was their average rate of speed in mph ​

Answer 1

Average speed is 12.6 miles per hour

Solution:

Given that team tool bella canoed
`15(3)/(4)` miles in
`(5)/(4)` hours

To find: average rate of speed in miles per hour

From given information,

`distance = 15(3)/(4) \text{ miles } = (15 * 4+3)/(4) = (63)/(4) \text{ miles}`

`time = (5)/(4) \text{ hours}`

To find the speed we use the below formula,

`speed = (distance)/(time)`

Substituting the given values we get,

`speed = ((63)/(4))/((5)/(4))\\\\speed = (63)/(4) * (4)/(5) = (63)/(5) = 12.6`

Thus average speed is 12.6 miles per hour
