car a runs at the speed of 80 km / hr & reaches its destination in 5 hr . car b runs at the speed of 100 km / h & reaches its destination in 2 h . what is the respective ratio of distances covered by car a & car b ?
"sol . distance travelled by car a = 80 × 5 = 400 km distance travelled by car b = 100 × 2 = 200 km ratio = 400 / 200 = 2 : 1 answer : c"
divide(multiply(80, 5), multiply(100, 2))
