Here is the formula you need.
((2:52+0:0:09) - (2:38+0:0:42)) x 0.04=answer
Add them up - Add them up x 0.04=answer
(2:52:09- 2:38:42) x 0.04=answer
Round to nearest min. - Round to nearest min. x 0.04=answer
(2:52 - 2:39) x 0.04 =answer
13 minutes x 0.04=answer
Answer = 0.52

The answer is b 0.52.
From 42 seconds after 2:38 to 9 seconds after 2:52 is 13 minutes and 27 seconds.
Rounding this off to the nearest minute is 13 minutes.
13 x 0.04 = 0.52
