Answers
By saying "125% more time", he is saying that the extra time he spent was 125% of the orginal amount.
Last week he spent 20 hours. This week, he spent 25 hours, 5 more hours.
Comparing the extra hours (5) to the hours that he spent last week (20): 5/20 = 25% extra time.
The hours that he spent this week, when compared to the hours last week, is 125%; but this isn't 125% more time.
