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

Answer:

$unit \: rate = \frac{distance}{time}$

substitute:

$unit \: rate = \frac{( \frac{1}{3} ) }{( \frac{1}{9}) } \\ \\ = \frac{1}{3} \div \frac{1}{9} \\ \\ = \frac{1}{3} \times 9 \\ \\ = { \underline{ \: \: 3 \: miles \: per \: hour \: \: }}$
