Expert Answer:

use the formula average speed = total distance /total time taken

d=500m and t=2hr10min for the first case for finding the average speed

d=700 and t=2hr11min for the second case for finding the average speed.

total distance = 700m and total time = time in first journey + time in second journey

by the above data find the average speed.  for different cases.
