car a runs at the speed of 35 km / hr & reaches its destination in 9 hr . car b runs at the speed of 43 km / h & reaches its destination in 10 h . what is the respective ratio of distances covered by car a & car b ?
"sol . distance travelled by car a = 35 × 9 = 315 km distance travelled by car b = 43 × 10 = 430 km ratio = 315 / 430 = 63 : 86 e"
divide(multiply(35, 9), multiply(43, 10))
