Martin is filling his bathtub, but he left the drain partially open. martin knows that it takes 8 minutes to fill his 40 gallon tub. the equation v = 2.5t represents the volume, v , of water that drains out of the tub in t minutes. if martin leaves the water on, will the tub ever overflow ? please someone help ​

Yes

Step-by-step explanation:

First, we know that 40 minutes = 8 gallons filled up. We have another equation, v=2.5t, that includes time and volume. If we can make the first equation in terms of time, we can figure out the relative speeds of water entering/exiting the bathtub.

To make 40 minutes = 8 gallons in terms of t, or minutes, we can divide both sides by 8 to get

5 minutes = 1 gallon

5t = v

Therefore, for water entering the tub, we get

5t = v, and for water draining out, we get

2.5t = v

As the time is always positive, the water entering the tub (5t) will always be greater than the water exiting the tub. Therefore, as more water goes in than out, the tub will gradually increase in water level and will eventually overflow
