A water tank holds 200 gallons but is leaking at a rate of 3 gallons per week. A second water tank holds
300 gallons but is leaking at a rate of 5 gallons per week. After how many weeks will the amount of water
in the two tanks be the same?
The amount of water in the two tanks will be the same in
weeks.

A Water Tank Holds 200 Gallons But Is Leaking At A Rate Of 3 Gallons Per Week A Second Water Tank Holds 300 Gallons But Is Leaking At A Rate Of 5 Gallons Per We class=

Sagot :

200-3w = 300-5w

Where w is the number of weeks

Rearrange and reduce:
-3w + 5w = 300-200
2 w = 100
w = 100/2 = 50 weeks
