Total distance moved = (10*2 + 15*3) km = (20 + 45) km = 65 km.Total time taken = (2 + 3) h = 5 h.Average speed = (65 / 5) km/h = 13 km/h.15 Views

Gn:Speed = 10 km/h
Time = 2 h
Hence, Distance = 20 km.
Now, Speed=15 km/h
Time = 3 h
Hence, Distance = 45 km.
Hence, total distance = 20+45 = 65 km.
Average speed = (10+15)/2 = 25/2
=12.5 km/h.
