Question

one lap around a 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

`unit \: rate = (distance)/(time) \\`

substitute:

`unit \: rate = (( (1)/(3) ) )/(( (1)/(9)) ) \\ \\ = (1)/(3) / (1)/(9) \\ \\ = (1)/(3) * 9 \\ \\ = { \underline{ \: \: 3 \: miles \: per \: hour \: \: }}`
