there is a train and car . the ratio btw the speed of a train & a car is 16 : 15 respectively . also , a bus covered a distance of 480 km in 8 h . the speed of the bus is 3 / 4 th of the speed of the train . how much distance will the car cover in 6 h ?
sol . speed of bus = 480 / 8 = 60 km / h speed of train = ( 60 * 4 ) / 3 = 80 km / h speed of train : speed of car = 16 : 15 speed of car = 80 / 16 * 15 = 75 km / h distance covered by car in 6 hr = 75 × 6 = 450 km e
multiply(divide(multiply(divide(multiply(divide(480, 8), 4), 3), 15), 16), 6)
