15
. 125 divided by 8 is 15.625,0,625 times 8 is 5, add 15 and 5/8 and get 15
.
Answer:
4.8
Step-by-step explanation:
add all values and divide it by 5
1054 (9-8x)=78
(9-8x)= (78÷1054)
9-8x = 0.074
-8x=0.074-9
-8x=-8.926
x= (-8.926÷-8)
x= 1.1157
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.
