Atube filled with 50 quarts of water empties at a rate of 2.5 quarts per min

it will be emte in 20 hours

Remark

If it does not have more water flowing in to take the place of the water flowing out, then the question can be solved by the formula below.

Formula

Total amount of water = the rate flowing out * the time to empty the container.

Givens

Amount of water = 50 quarts

Rate = 2.5 quarts / min

Solve

50 = 2.5 * t

t = 50 / 2.5

t = 20 quarts per minute. But there is a lot of possible variation to this question.

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
