Average rate of speed is equal to total distance divided by the total time. the total distance is equal to 4.5+7.5, or 12 miles. The total time from 8:00 to 8:48 is 48/60 of one hour. 12*60/48=15 miles per hour

Answer : The bicyclist's average rate of speed in miles per hour is 15 mile/hr.

Step-by-step explanation:

Average rate if speed : It is defined as the ratio total distance to total time.

Formula used :

As per question,

Total distance traveled by bicyclist = 4.5 mile + 7.5 mile = 12 mile

Total time taken by bicyclist = (8:48 A.M - 8:00 A.M) = 48 min = 0.8 hr

conversion used : ( 1 hour = 60 minute)

Now put all the given values in the above formula, we get the bicyclist's average rate of speed in miles per hour.

Therefore, the bicyclist's average rate of speed in miles per hour is 15 mile/hr.
