in 1 min tub is filled by faucet =1/15
in 1min water drained out from tub by hole=1/18
if both are working at the same time then water filled in the tub in 1 min=(1/15)-(1/18)=?

the faucet is filling it up in 15mins
the hole is draining it in 18mins

so that means the faucet is going at a faster rate, since it takes less time to fill it up

anonymous · Answer

wait so would it be (1)/(1/15-1/18)=x ?

jdoe0001 · Answer

so if you check how much each does in 1 minute,  you'd get the rate at which is filling up
