How many metres would it take for car A (travelling at a constant 100km/hr) to end up 52.78m in front of car B (travelling at a constant 95km/hr) if car B had a headstart of 55.56m?
-------------------------
Find how much time it takes first.
------------
Car A is moving 5 km/hr relative to car B (100 - 95)
52.78 + 55.56 = 108.34 meters = 0.10834 km to the point ahead of car B
0.10834 km/5 km/hr = 0.021668 hr
----------------
Car A travels 100km/hr for 0.021668 hr
d = 2.1668 km
d = 2166.8 meters
