car a runs at the speed of 52 km / hr & reaches its destination in 10 hr . car b runs at the speed of 46 km / h & reaches its destination in 8 h . what is the respective ratio of distances covered by car a & car b ?
"sol . distance travelled by car a = 52 × 10 = 520 km distance travelled by car b = 46 × 8 = 368 km ratio = 520 / 368 = 65 : 41 d"
divide(multiply(52, 10), multiply(46, 8))
