Can I get to the Palace Museum in Phnom Penh for half a day?

Seven dollars for a taxi, four and a half dollars for a motorcycle, and seven dollars for others to come back from the airport by tutu. Both the Forbidden City and the Museum open at 9: 00, close at 12: 00 and open again in the afternoon. It takes two hours for the Forbidden City and one hour for the museum. The two places are very close, but if you take the 12: 30 bus, they will give you about half an hour to pick you up. You certainly don't have enough time. No matter where you go to Phnom Penh, one and a half hours is enough.
