500/100 equals 5, so 5.6 times 5 equals 28.
Using the together rate, it is found that the time it would take the second pump, working alone, to fill the tank is:
B. 90 minutes
The <em>together rate</em> is the <u>sum of each separate rate</u>.
In this problem:
- The together rate is of 1/60.
- The first rate is of 1/150.
- The second rate is of 1/x.
Then:
Applying cross multiplication:
Hence, it would take 90 minutes for the second pump, working alone, to fill the tank.

Step-by-step explanation:
Answer: It will take him 1.68 years to recover his initial investment.
First, find the amount of extra money that he will make.
34,000 - 13,000 = 21,000
He will be making an extra 21,000 per year.
Now, divide the cost of his training by the amount of his increase.
35200 / 21000 = 1.68
That gives you the amount of years it will take him to pay off his investment.
