Question
A boy goes to school with a speed of 60 km/h and comes
back with a speed of 40 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 60 x 40)/(60 + 40) Average speed = (2 x 60 x 40)/100 = 48 km/hr
