We are looking for the ratio of the number of minutes he lifted weights to the total number of minutes of his entire workout.

We read that he lifted weights for 25 minutes.
Now we need to total time of his workout.

Total time = warm up time + lifting weights time + treadmill time
Total time = 10 mn + 25 mn + 15 mn = 50 mn

Now we know he lifts weights for 25 minutes, and has a total workout time of 50 minutes.

The ratio of the time of lifting weights to the total time is
25:50

We divide both sides by 25 to reduce the ratio to
1:2

Answer is B: 1:2
