Answer:
All speed from 0 mi/h and 11 mi/h were reached because the initial and final speed was 0 mi/h the speed of 10 mi/hr was reached at least twice in the race.
Step-by-step explanation:
Given,
Total distance covered = 6.2 miles,
Time taken = 34 minutes = hours
( 1 hour = 60 minutes )
Since,
Thus, the speed of the runner =
= 10.9411764706
≈ 11 miles per hour
Thus, the average speed of the runner is 11 miles per hour ( approx )
By MVT,
The speed was exactly 10 mi/hr at least twice in the race.
By intermediate value theorem,
All speed from 0 mi/h and 11 mi/h were reached because the initial and final speed was 0 mi/h the speed of 10 mi/hr was reached at least twice in the race.
