Question
A train covers a certain distance at a speed of 20 km/h
and the next same distance with a speed of 35 km/h and the next same distance with a speed of 60 km/h. find the average speed?Solution
Since the distance is same in all the conditions. Therefore, Average speed = 3xyz/(xy + yz + zx) Average speed = 3 x 20 x 35 x 60/(20 x 35 + 35 x 60 + 20 x 60) Average speed = 3 x 20 x 35 x 60/(700 + 2100 + 1200) = 126000/4000 = 31.5 km/hr
