Question

A tank had 6 liters of water. The tank had a small hole in its base through which water leaked out at a constant rate. The tank was empty after 4 minutes. If y represents the number of liters of water in the tank and x represents the time in minutes, which graph best represents this situation?

Answer 1

Based on the given problem above, if we analyze it, we are going to look for the graph which with coordinates (0,6) which represents starting out with 6 gallons, and ending at (4,0). So, the graph that best represents this situation would be the first graph on the top left. Hope this answers your question. Have a great day!

Answer 2

Option A

Explanation:

Given : A tank had 6 liters of water and tank has small hole. The tank was empty after 4 minutes.

If y represents the number of liters of water in the tank.

x represents the time in minutes.

From the following graph option A is correct (also attached below)

Because when we notice in all the graph y represent the number of liters of water in tank and we have 6 liters of water ⇒y=6

And water is leaked out at a constant rate which means a decreasing slope.

The tank was empty after 4 minutes and time denote by x-axis therefore, x=4 and tank is empty means y=0

Therefore, the graph in which from y=6 with a decreasing slope at x=4 , y=0

Option A is the only one representing the situation.
