Question

Team Tool Bella canoed 15 3/4 miles in 5 1/4 hours. What was their average speed in miles per hour

Answer 1

Thee miles per hour

Answer 2

we know that

To find the average speed divide the total distance by the time

In this problem we have

`total\ distance=15(3)/(4)\ miles`

`time=5(1)/(4)\ hours`

Convert mixed numbers to an improper fractions

`total\ distance=15(3)/(4)\ miles=(15*4+3)/(4) =(63)/(4)\ miles`

`time=5(1)/(4)\ hours=(5*4+1)/(4) =(21)/(4)\ hours`

Divide the total distance by the time

`((63/4))/((21/4)) =(63)/(21) =3(miles)/(hours)`

therefore

the answer is

the average speed is
`3(miles)/(hours)`
