Answer:
Step-by-step explanation:
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.

Answer:
1 < x < 4 . . . . {x | x < 4 <u>and</u> x > 1}
Step-by-step explanation:
We want to write the answer as a compound inequality, if possible. As it is written, we can solve each separately.
x + 1 < 5
x < 4 . . . . . . . subtract 1
__
x -4 > -3
x > 1 . . . . . . . add 4
So, the solution is ...
(x < 4) ∩ (x > 1) . . . . . . the intersection of the two solutions
As a compound inequality, this is written ...
1 < x < 4
