The times of take-off and landing of aircraft are given in local times. A plane leaving Montreal at 7 pm arrives in Paris at 8 am. Assuming that the travel time is the same in both directions, what time would a plane leaving Paris at 11 am arrive in Montreal? |

For instance, it is 12 noon in M while it is 6p.m. in P, and that means in P it's 6 hours later than it is in M. With the next thing you give, leaving Montreal at 7pm means leaving M at 1am by P time(7pm + 6hours = 13pm = 1am). So, by the easiest consideration, the travel time is 8am - 1am = 7hours. The second plane leaves Paris at 11am, so it arrives at M at 11 + 7 = 18am = 6pm by P time. So by M time, this 6pm should be 6pm - 6hours = 12pm. Right? |
