Im struggling to answer these 4, ? win 50 points!

1) Jacques Timing between B & C = 3:28 - 1:53 = 1 h 25 m
Eddy timing = 3:02 - 1:41 = 1 h 21 m

It would be 4 minutes

2) Total time he takes = 2h49m + 1h18m + 1h21m = 5h28m
So, time when he finished  = 11:15 + 5:28 = 4:43 PM

3) Jacques arrive at = 3:28
So, 11 minutes before that = 3:17

Then, 3:17 + 1:28 = 4:45 PM

4) Jacques finished at = 4:43

So, Lance = 4:43 - 4h54m = 11:49

Hope this helps!
