Question
A train covers a certain distance at a speed of 8 km/h
and the next same distance with a speed of 14 km/h and the next same distance with a speed of 24 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 8 x 14 x 24/(8 x 14 + 14 x 24 + 8 x 24) Average speed = 3 x 8 x 14 x 24/(112 + 336 + 192) = 8064/640 = 12.6 km/hr
