Maureen spends four times as long riding the train each day as riding the bus. If she spends 75 minutes on the bus and the train

yulyashka [42]

Answer:

60 minutes or 1 hour

Step-by-step explanation:

Set x as the amount of time she spends riding the bus

75 = time on bus + time on train

She spends 4 times as long on the train as on the bus so the time she spends on the train is 4x

75 = x + 4x

75 = 5x

x = 15 minutes on the bus

Since she spends 4 times as long on the train, we do 4 x 15 and we get 60 minutes which is 1 hour
