Answer 1

ANSWER:

✔ 1 over 3 ⋅ 12 hours

EXPLANATION:

1/12 of a tank in 20 minutes.

Thus we know in an hour, an oil company can fill 3/12 of a tank (60 minutes in an hour).

3 x 4 = 12, and 12/12 = 1(a whole tank),

so we multiply 1 (hour) by 4.

Our answer is that it takes 4 hours to fill a tank.

Answer 2

Answer:

4 hours

Step-by-step explanation:

1/12 time what equals 1? 12 so do it to the other equation and simplify 12/3 to get 4.
