Answer:
First calculate the distance for each of these speeds:
25 km/hr x 4 min x 1 hr/60 min = 1.67 km
50 km/hr x 8 min x 1 hr/60 min = 6.67 km
20 km/hr x 2 min x 1 hr/60 min = 0.67 km
Now sum the distances for total distance covered = 9 km.
Average speed = total distance/total time
= 9 km / 14 min = 0.643 km/min x 60 min/hr = 38.57 km/hr
Hope it helps you
