1.	a motorcyclist drives from A to B with a uniform speed of 30 km per hour and return from place B to a with uniform speed of 20 km per hour find his average speed
Answer» Let the distance TRAVELLED be d No the TIME taken at the FIRST is T1=d/30 and T2=d/20 Avg speed =(d+d)/d/30+d/20 =2d/5d*60=24m
