Question
A boy goes to school with a speed of 65 km/h and comes
back with a speed of 35 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 65 x 35)/(65 + 35) Average speed = (2 x 65 x 35)/100 = 45.5 km/hr
