Water flowed out of a tank at a steady rate. A total of 18 1/2 gallons flowed out of the tank in 4 1/4 hours. Which expression

Alecsey [184]

Answer:

In 1 hour water flowed out = $\frac{74}{17}$ gallons

Step-by-step explanation:

Given as ,

The quantity of water flowed out of tank = 18 $\frac{1}{2}$ gallons

= $\frac{37}{2}$ gallons

The time spend in flowing water out of tank = 4 $\frac{1}{4}$ hours

= $\frac{17}{4}$ hours

∵ In $\frac{17}{4}$ hours , water flowed out = $\frac{37}{2}$

∴ In 1 hours , water flowed out = $\frac{37\times4} {17\times2}$

So, in 1 hour water flowed out = $\frac{74}{17}$ gallons Answer
