Two trains start from the same point and travel in opposite directions. Train A travels at 80 km/h and Train B at 100 km/h. How far apart will they be after 2 hours?
Answer: A. 360 km
Distance covered by Train A = 80 km/h * 2 hours = 160 km; Distance covered by Train B = 100 km/h * 2 hours = 200 km; Total distance apart = 160 km + 200 km = 360 km.
