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 minutes, around the track?

Answer 1

rate = speed = v = distance / time = d/t

 

d = 1/3 mile

 

t = 1/9 hour

 

v = d/t = (1/3 mile) / (1/9 hour) = 3 miles/hour = 3 miles / (60 minutes) = 0.05 miles/minute
