Maya can run 18 miles in 3 hours and she can bike 18 miles in 2 hours. When Maya biked for 3 hours and ran for 1 hour and 30 min what was her average speed?

Answer 1

To find Maya's average speed, we first need to calculate the total distance she traveled and the total time she took to cover that distance.

When Maya biked for 3 hours, she covered 18 miles. So, her biking speed was 18 miles / 2 hours = 9 miles/hour.

When Maya ran for 1.5 hours (which is equivalent to 1 hour and 30 minutes), she covered 18 miles. So, her running speed was 18 miles / 3 hours = 6 miles/hour.

Total distance covered = 18 miles (biking) + 18 miles (running) = 36 miles
Total time taken = 3 hours (biking) + 1.5 hours (running) = 4.5 hours

Average speed = Total distance / Total time
Average speed = 36 miles / 4.5 hours
Average speed = 8 miles/hour

Therefore, Maya's average speed when biking for 3 hours and running for 1 hour and 30 minutes was 8 miles per hour.
