Question
A boy goes to school with a speed of 70 km/h and comes
back with a speed of 55 km/h. find his average speed?Solution
Since the distance travelled by a boy (going to school and coming back from school) is equal. So, average speed = 2xy/(x + y) Average speed = (2 x 70 x 55)/(70 + 55) Average speed = (2 x 70 x 55)/125 = 61.6 km/hr
