Question

One lap around the dirt track is 1/3 mile. It takes Bryce 1/9 hour to ride one lap. What is Bryce's unit rate, in miles, around the track?

Answer 1

Bryce's speed (slow speed I might add) is `3` miles per hour.

Explanation:

`s = d/t` where `s` is speed, `d` = distance and `t` = time.

Solving for `s` gives:
`s = (1/3) / (1/9)`

`s = 9/3`

`s = 3` miles per hour
