The Smart Scholar Method
If the ships had not collided but had crossed each other and proceeded at speeds of 84 and 48 kmph, in 15 minutes (03:07 - 02:52), they would have covered (84 + 48)/4 = 33 kms. This is the distance that separated them 15 minutes after they crossed each other and hence the distance that separated them 15 minutes before the accident.
