Answer:
Number of gallons left in tank after m minutes [tex]35 -\frac{m}{4}[/tex]
Step-by-step explanation:
Given:
A tank containing 35 gallons of water.
Total water in tank = 35 gallons
In 1 minute =[tex]\frac{1}{4}[/tex] gallons
In m minute = Rate of Leakage in tank in m minutes
By using Unitary Method we get,
Rate of Leakage in tank in m Minutes = [tex]\frac{m}{4}[/tex]
Number of gallons left = Total water in tank - Rate of Leakage in tank in m Minutes = [tex]35 - \frac{m}{4}[/tex]
Number of gallons left in tank after m minutes [tex]35 -\frac{m}{4}[/tex]
