Your answer

A number or a short expression. Fractions can be typed as 3/2, and spacing doesn't matter.

Solution

We add 25 minutes to 1 hour and 48 minutes in two steps.

First, we add 12 minutes to 1 hour and 48 minutes to get 2 hours.

Then we add $25 - 12 = 13$ minutes to
2 hours to get 2 hours and 13 minutes.

Alternatively, we could note that 1 hour and 48 minutes is $60 + 48 = 108$ minutes, and so the time
that is 25 minutes longer is 133 minutes, which is $120 + 13$ minutes or 2 hours and 13
minutes.
