Question

A 14.1 liter fish tank is being filled by 2 water faucets. Water flows out of Faucet A at the rate of 140 milliliters per minute. Water flows out of Faucet B at the rate of 100 milliliters per minute. How long will it take the two faucets to fill the fish tank completely? (1 liter = 1000 milliliters)

Answer 1

58.75 minutes

Explanation:

It is given that the volume of the fish tank is 14.1 liter = 14.1 × 1000 milliliters

Volume of water flows out from faucet A in one minute = 140 milliliters

Volume of water flows out from faucet B in one minute = 100 milliliters

Total volume of water flows out from both the faucets = 140 + 100 = 240 milliliters

Time taken to fill the tank =
`(Volume of the fish tank)/(Volume of water flows out from both faucets)`

=
`(14.1(1000))/(240)`

= 58.75 minutes
