car a runs at the speed of 50 km / hr and reaches its destination in 8 hours . car b runs at the speed of 60 km / h and reaches its destination in 4 hours . what is the ratio of distances covered by car a and car b ?
"car a travels 50 × 8 = 400 km car b travels 60 × 4 = 240 km the ratio is 400 : 240 = 40 : 24 = 5 : 3 the answer is d ."
divide(multiply(50, 8), multiply(60, 4))
