The Solution

The accident must have occurred 528/(84 + 48) = 4 hours after the ships set off, that is, at 11:07 pm. The gap between then and 02:52 am is 3 hours and 45 minutes. During this period, the British ship must have travelled 84 x 3¾ = 315 kms and the German ship must have travelled 48 x 3¾ = 180 kms. Therefore at 02:52 am, the ships must have been 528 – (315 + 180) = 33 kms apart.
