Answer:
sorry don't know the answer
40 people are needed to fill the water tank in 5 hours.
Let's first define some variables to make the problem easier to solve. Let's call the number of people needed to fill the water tank in 5 hours "x".
We know that 10 people can fill the water tank in 20 hours, which means that their combined rate of filling the tank is:
10 people * 20 hours = 200 people-hours
Now, let's consider how much water can be filled by "x" people in 5 hours. Their combined rate can be expressed as:
x people * 5 hours = 5x people-hours
We know that the amount of water to be filled is the same in both cases, so we can set the two expressions equal to each other:
200 people-hours = 5x people-hours
Solving for x, we get:
x = 200/5
x = 40
Therefore, 40 people are needed to fill the water tank in 5 hours.
