A tank was filled with 20L of water. However, there was a hole and 2/3L was leaked out every minute.How long did it take for the tank to become empty?
Answered by amper
FIRST,look for the unit

L----Litre

leak?L per minute-------L m^-1

that mean

L/ L m^-1

=1/ m^-1

=m

therefore,
ans:
20/(2/3)
=30minutes.
