Question

Team tool bella canoed 15 3/4 miles in 5 1/4 hours. What was their average rate of speed in mph

Answer 1

Team Tool Bella's average rate was 3 miles per hour.

Answer 2

Answer: The average rate of speed is 3 miles per hour.

Step-by-step explanation: Given that the team tool bella canoed
`15(3)/(4)` miles in
`5(1)/(4)` hours. We are given to find the average rate of speed in miles per hour (mph).

We will be using unitary method to solve the given problem.

Now,

`15(3)/(4)=(63)/(4),~~~~~5(1)/(4)=(21)/(4).`

According to the question,

In
`(21)/(4)` hours, number of miles canoed by the team is

`=(63)/(4)~\textup{miles}.`

Therefore, in 1 hour, number of miles canoed by the team is given by

`((63)/(4))/((21)/(4))=(63)/(4)* (4)/(21)=3~\textup{miles}.`

Thus, the average rate of speed is 3 miles per hour.
