Answer:
A. w = 50 - 2.5t
B. For t = 30 minutes there is no viable solution.
Step-by-step explanation:
A. A tub is filled with the amount of water = 50 quarts
Rate at which the tub is getting emptied = 2.5 quarts per minute
Let the time taken to empty the tub = t minutes
Then amount of water leaked from the tub in t minutes = 2.5t
If w quarts is the amount of water left in t minutes then equation will be
w = 50 - 2.5t
B. To calculate the time to get the tub emptied w = 0
then 50 - 2.5t = 0
2.5t = 50
t =
t = 20 minutes
Therefore, for time t = 30 minutes there is no viable solution because the tub will be emptied in 20 minutes.
