# Minutes Inbetween

##### Stage: 2 and 3 Short Challenge Level:

Two complete hours takes you to $13:41$. Then, another 19 minutes takes you to $14:00$, and another 2 minutes to $14:02$.

As there are 60 minutes in an hour, the two hours is the same as 2 x 60 = 120 minutes, so the total time is 120 + 19 + 2 = 141 minutes.
