one faucet can fill the bath in 6 minutes and the other faucet in 15 minutes. how long will it take the bath if both faucets are running?

i think the difference between the time is the answer
if the other faucet is 6 mins. to fill the bath and the other is 15 mins.,then its time will combine,the answer is 9 mins.
