PLEASE HELP, I DON'T UNDERSTAND THE WORDING​

Answer 1

C. 8 miles per hour

Explanation:

It takes Diego
`(1)/(8)` of an hour to complete the lap =
`(1)/(8)` x 1 hour =
`(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 =
`(distance)/(time taken)`

=
`(1)/((1)/(8) )`

= 8

Speed = 8 mile per hour

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