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 all together, how long did she spend riding the train

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

the square root of what number? if you add that, then someone will probably answer the question.
