Answer:
3 minutes and 30 seconds
Step-by-step explanation:
7-5 = 2
3/2 = 1.5 gallons that empty per each minute
1.5 times 3 (minutes) = 4.5 gallons emptied
Remaining gallons to empty = 0.5
0.5 gallons to empty will take 30 seconds

Correct answer: 210 ways
Step-by-step explanation:
We will solve this using a combination without repetition (n k) / k!
The total number of combinations is
(10 1) · (7 5) / 5! = 10 · (7 2) / 2! = 10 · (7 · 6)/ 2 = 10 · 42/ 2 = 10 · 21 = 210
God is with you!!!
