Question

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?

Answer 1

Answer:

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
