Answer:
It took Anne 1/30 of an hour to bike 1 mile.
Step-by-step explanation:
Unit Rate - 30 miles/ 1 hour

Based on the visual above, we need to find the proportion.
30 miles divided 30 equals to 1 mile.
What is 1 hour divided by 30? Remember: <u>whatever is done to the numerator must be done to the denominator</u>!
1 divided by 30 equals 1/30. Since the unit is hour, the answer is 1/30 <em>of</em> an hour.
