Question 1
Car A at 68 km/h and Car B at 63 km/h start from the same point in the same direction. How long will it take for them to be 395 km apart?
Step-by-step:
1. Relative speed when moving in same direction = |63 - 68| = 5 km/h
2. Time = Distance / Relative Speed = 395 / 5 = 79.0 hours
3. The first car will be 395 km ahead after 79.0 hours
