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
<u>Now, According to question</u>
∵ 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
