Answer:
The required linear equation is : y = 20x
Volume of water after 5 seconds = 100 cm³
Step-by-step explanation:
Volume of water collected in tank in 1 second = 20 cm³
Volume of water collected in tank in x second = 20x cm³
Now, it is given that volume of water collected in tank in x second is y cm³
So, the required linear equation is : y = 20x
Now, volume of water after 5 sec : so x = 2
⇒ y = 20 × 5
⇒ y = 100 cm³
Hence, Volume of water after 5 seconds = 100 cm³
Verified answer
First eq. will be x+y=20(x+5)+y=20+5 will be second eq.
