Question

1. kate’s skating rink has a circular skating rink that is \\(\frac{1}{5}\\) mile long. kayla skates on this rink, completing each lap in \\(\frac{1}{20}\\) of an hour. what is kayla’s skating speed? include the unit of measure.

Explanation:

Step1: Recall speed formula

Speed = $\frac{\text{Distance}}{\text{Time}}$

Step2: Substitute given values

Distance = $\frac{1}{5}$ mile, Time = $\frac{1}{20}$ hour
$\text{Speed} = \frac{\frac{1}{5}}{\frac{1}{20}}$

Step3: Simplify the fraction

Dividing by a fraction = multiply by its reciprocal:
$\text{Speed} = \frac{1}{5} \times 20$
$\text{Speed} = 4$

Answer:

4 miles per hour
