Answer:

Explanation:

I did this quickly so you'd get an answer so appologies for any errors.

1. The change from 7 gallons to 5 is -2/3 or -.667 a minute because it decreases 2 gallons in 3 minutes.

2. 5 gal = (2/3 gal/min)(x minutes)

x = 5(3/2) = 15/2 = 7.5 minutes to drain the remaining 5 gallons.

3. There was 10 gallons when the tank is full

That is 3 gallons more than the 7 gals there when Jada arrived.

(2/3)(x) = 3

x = 3(3/2) = 9/2 = 4 1/2 minutes

4 1/2 minutes before Jada arrived
