Mallory needs to go to the airport. It takes her 120 minutes to get there by car. This is 3 times the time it takes by
seraphim [82]

It will take Mallory 40 minutes to get to the airport by train.

Step-by-step explanation:

Time taken by car = 120 minutes

Time taken by train = t

According to given statement;

Time taken by car = 3 times time taken by train

120=3t

Dividing both sides by 3

It will take Mallory 40 minutes to get to the airport by train.
