A family must catch a train on the other side of a river. The train is leaving in 30 minutes. They have been joined by their friend, a cop who want to help them cross the river.
RULES
1.The cop can cross the river in 1minute,father in 3 minutes, mother in 6 minutes, daughter in 8 minutes and son in 12 minutes
2.If two people are on the raft,they will cross the river in the time that it would take for the slower person to cross alone....
CAN YOU HELP THE FAMILY CATCH THEIR TRAIN??????

Let me try and see if i am a genius
First the logic of the question is (go with heavy and return with light) how? This way,take.
A cop+father=return with cop
A cop+mother=return with cop
Put a son himself then return with father then
Father +daughter then all the family members will cross and they will remain with only one minute to catch the train because the cop only help them to cross but not cross himself .
