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

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

Step-by-step explanation:  Given that the team tool bella canoed $15\dfrac{3}{4}$ miles in $5\dfrac{1}{4}$ 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,

$15\dfrac{3}{4}=\dfrac{63}{4},~~~~~5\dfrac{1}{4}=\dfrac{21}{4}.$

According to the question,

In $\dfrac{21}{4}$ hours, number of miles canoed by the team is

$=\dfrac{63}{4}~\textup{miles}.$

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

$\dfrac{\frac{63}{4}}{\frac{21}{4}}=\dfrac{63}{4}\times \dfrac{4}{21}=3~\textup{miles}.$

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

Answer 2

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