hi @habibmaham2345_bcec1af6a2a781b5 u can measure 11 first with 1 hr glass and then at the same time turn both 7 and 11 hr glass the moment 7 hr glass gets empty it means 7 mins passed in 11 hr glass also and rest 4 mins will be remaining.

Now u can use this hr glass ( with 4 mins remaining ) to measure 15 ( 4 + 11 )
