Answer 1

a. 2 hours

Explanation:

All you have to do is find the median between 40 minutes on Saturday, 1 hour 20 minutes on Monday, and 2 hours on Wednesday.

The median is 2. Therefore 2 hours is the answer.

Answer 2

D because each day he runs for 40 more minutes. To explain, if you add 40 minutes to 40 minutes, you get 80 minutes, or 1 hour and 20 minutes. Then if you add 40 minutes to 1 hour and 20 minutes you get 1 hour and 60 minutes, or 2 hours. Continuing this process, the next logical answer would be 2 hours and 40 minutes.
