Step-by-step explanation:
Given parameters:
Distance of store = 5miles
Time to store =
hr
Time from store =
hr
Unknown:
Average speed = ?
Solution:
Average speed is the total distance divided by the total time taken.
Average speed =
Total distance = distance to store + distance from store = 5 + 5 = 10miles
Total time taken =
hr +
hr =
hr
Average speed =
= 10 x
= 11.1m/s
