Answer:
3 miles per hour
Step-by-step explanation:
Using speed formula:
[tex]\text{Speed} = \frac{\text{Distance}}{\text{Time}}[/tex]
As per the statement:
Team tool Bella canoed 15 3/4 miles in 5 1/4 hours.
⇒[tex]\text{Distance} = 15\frac{3}{4} = \frac{63}{4}[/tex] miles and
[tex]\tetx{Time} = 5\frac{1}{4} = \frac{21}{4}[/tex] hours
Using speed formula we have;
[tex]\text{Speed}= \frac{\frac{63}{4} }{\frac{21}{4}} = \frac{63}{4} \cdot \frac{4}{21} = \frac{63}{21}[/tex]
Simplify:
[tex]\text{Speed} =3[/tex] miles per hour
Therefore, their average rates of speed in miles per hour is, 3 miles per hour
