Maths Problem 1
A boy goes to the school with the speed of 3 km/hr and returns with the speed of 2 km/hr. If he takes 5 hours, in all, then how do you find the distance (in km) between house to the school? Answer :- Let the distance be x km S 1 = 3km/h S 2 = 2km/h d = x km d = x km t 1 = d/s = d/3 t 2 = d/s = d/2 Total Time = t 1 +t 2 = 5 ð => d/2 + d/3 = 5 ð 3x + 2x / 6 = 5 ð 5x = 30 ð x = 30/5 = 6 km the distance between house to the school is 6 km
