Watson is filling a huge beaker. The water comes out of the faucet at a steady rate. The beaker starts empty. He notices that after five seconds there is 420cm of water in the beaker. How much water will be in the beaker after 12 seconds?

Respuesta :

1008 cm water will be in the beaker after 12 seconds

Solution:

Step 1:

Given data: The beaker starts empty.

Quantity of water in the beaker after 5 seconds = 420 cm

Step 2:

Quantity of water in the beaker after 1 second  = [tex]\frac{420}{5}[/tex] cm

Quantity of water in the beaker after 1 second = 84 cm

Step 3:

Quantity of water in the beaker after 12 second = 84 cm × 12

Quantity of water in the beaker after 12 second = 1008 cm

Hence, 1008 cm water will be in the beaker after 12 seconds.
