Two cars start from the same point and travel in opposite directions. If one car travels at 70 km/h and the other at 50 km/h, how far apart will they be after 2 hours?
Answer: A. 240 km
In 2 hours, the first car travels 140 km and the second car travels 100 km. Total distance = 140 km + 100 km = 240 km.
