Answer 1

Answer:

C. 8 miles per hour

Step-by-step explanation:

It takes Diego $\frac{1}{8}$ of an hour to complete the lap = $\frac{1}{8}$ x 1 hour = $\frac{1}{8}$ hour

Distance of the track = 1 mile long

The speed of an object expresses the ratio of distance moved to time taken to cover the distance.

i.e speed = $\frac{distance}{time taken}$

           = $\frac{1}{\frac{1}{8} }$

           = 8

Speed = 8 mile per hour

Therefore, Diego's bike has a speed of 8 miles per hour.
