car a runs at the speed of 65 km / hr & reaches its destination in 8 hr . car b runs at the speed of 70 km / h & reaches its destination in 5 h . what is the respective ratio of distances covered by car a & car b ?
"sol . distance travelled by car a = 65 ã — 8 = 520 km distance travelled by car b = 70 ã — 5 = 350 km ratio = 520 / 350 = 52 : 35 b"
divide(multiply(65, 8), multiply(70, 5))
