She walk 3 miles in 45 min what was her average rate in min per miles? in miles per hour?

Step 1. speed = distance/time

Step 2. Given, 1 hour = 60 minutes then 45 minutes* 1 hour/60 minutes = 0.75 hour

Step 3. Speed or average rate = 3 miles/(0.75 hour)=12/3 mph= 4 mph

Step 4. ANSWER: The average rate is 4 miles per hour.

I hope the above steps and explanation were helpful.
