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

Step-by-step explanation:

Given,

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

\frac{120}{3}=\frac{3t}{3}\\40=t\\t=40

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