Suppose 4.6 liters of water come out of a faucet each minute. For how many minutes was the faucet on if 52.9 liters of water came out?

Answer 1

The faucet would be on for 11.5 minutes for 52.9 liters of water to come out.

The formula for this is #l = 4.6t# where #l# is the number of liters from the faucet and #t# is the time or number of minutes the faucet was on. Substituting what is known and solving gives:

#52.9 = 4.6t#

#52.9/4.6 = 4.6t/4.6#

#11.5 = t#
