a boy goes to his school from his house at a speed of 3 km / hr and return at a speed of 2 km / hr. if he takes 5 hours in going and coming, the distance between his house and school is?
multiply(divide(5, add(divide(3, 2), const_1)), 3)
average speed = 2 * 3 * 2 / 3 + 2 = 12 / 5 km / hr distance traveled = 12 / 5 * 5 = 12 km distance between house and school = 12 / 2 = 6 km answer is b
