car a runs at the speed of 33 km / hr & reaches its destination in 7 hr . car b runs at the speed of 44 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 = 33 × 7 = 231 km distance travelled by car b = 44 × 5 = 220 km ratio = 231 / 220 = 21 : 20 c"
divide(multiply(33, 7), multiply(44, 5))
