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

As you can see the length of the one with the man is 6 and the length with the lamp post is 18 and we know that if you divide 18 by 6 you get 3 so then you mutiply 5.25 by 3. Then you get 15.75
Therefore the answer is A. 15.75
To find the equation of a line, you need to find the slope and y-intercept by using the slope formula and point slope formula.
First, let's find the slope. 11 + 5/9 - 1 = 16/8 = 2. Therefore, the slope is 2.
Then, plug it into the point slope formula.
y + 5 = 2(x - 1).
Distribute: y + 5 = 2x - 2
Subtract 5 on both sides: y = 2x - 7.
Your final equation, that you need to plug into your answer, is y = 2x - 7.
