Abicyclist started riding at 8: 00 a. m. the diagram below shows the distance the bicyclist had traveled at different times. what was the bicyclist's average rate of speed in miles per hour? 8: 00 a. m. < 4.5 > 8: 18 a. m. < 7.5 > 8: 48 a. m. the average rate of speed is 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.
