Julisha poured 1.5 liters of water into an empty flask. She boiled the water for 20 minutes then measured the amount of water that remained. She found that 70% of the water remained in the flask. Measured in liters, how much water evaporated?

Hope this ; )

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
