the height of the water in a fish pod is 42.5 inches. water is being drained from the pond at a rate of 3.75 inches per minute. what is the height of the water after 3 minutes?

The height of water after 3 minutes of drain is 31.25 inches.

Step-by-step explanation:

Given as:

The initial height of water in a fish pod = i = 42.5 inches

The rate of drain of water = r = 3.75 inches per min

Let The height of water after 3 min = f inches

The time taken for water drain = t = 3 minutes

Now, According to question

∵ In 1 minute, The water decreases = 3.75 inches

∴ In 3 minute, The water decreases = 3.75 inches * 3

I. e In 3 minute, The water decreases = 11.25 inches

Now, The height of water after 3 min = initial height of water - the decrease height of wate

f = i - 11.25 inches

Or, f = 42.5 inches - 11.25 inches

or, f = 31.25 inches

So, The height of water after 3 min = f = 31.25 inches

Hence, The height of water after 3 minutes is 31.25 inches Answer
