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
