The combined time taken if Mario and Ben work together will be 1.875 days.
<u>Time taken</u>:
- Mario alone = 3 days
- Ben alone = 5 days
<u>Work rate</u> :
- Rate = 1 / time taken
- Mario's rate = 1 / 3
- Ben's rate = 1/5
<u>Their combined rate can be written thus</u> :
- Mario's rate + Ben's rate = combined rate
- 1/3 + 1/5 = 8/15
<u>Time taken if they work together</u> :
- Reciprocal of combined work rate
- Combined time taken = 1 ÷ 8/15 = 15/8 = 1.875 days
Therefore, the time taken of they work together is 1.875 days
