car a runs at the speed of 50 km / hr & reaches its destination in 8 hr . car b runs at the speed of 25 km / h & reaches its destination in 4 h . what is the respective ratio of distances covered by car a & car b ?
"sol . distance travelled by car a = 50 × 8 = 400 km distance travelled by car b = 25 × 4 = 100 km ratio = 400 / 100 = 4 : 1 answer : a"
divide(multiply(50, 8), multiply(25, 4))
