Question

a runner completes $\frac{1}{2}$ mile in $\frac{1}{2}$ hour. how many miles does the runner complete in 1 hour?

Explanation:

Step1: Recall speed formula

Speed \( v = \frac{\text{distance } d}{\text{time } t} \). Here, \( d = \frac{1}{2} \) mile, \( t = \frac{1}{2} \) hour.

Step2: Calculate speed

Substitute values: \( v = \frac{\frac{1}{2}}{\frac{1}{2}} = 1 \) mile per hour.

Step3: Find distance in 1 hour

Using \( d = v \times t \), with \( v = 1 \) mph and \( t = 1 \) hour, \( d = 1\times1 = 1 \) mile.
