    okay, for q7(a)(III), i got t = 4:28. thus the time that the ship leaves is 4:28 after 1:00am, making the answer 5:28. why isn't this right?

    anyone worked out Q7 (a) (iii)?

    the time value i got for 7 was 4:28, but isn't that the time after 1:00am that the ship must leave, hence making the leaving time 5:28
