Question 1
Car A at 58 km/h and Car B at 51 km/h start from the same point in the same direction. How long will it take for them to be 392 km apart?
Step-by-step:
1. Relative speed when moving in same direction = |51 - 58| = 7 km/h
2. Time = Distance / Relative Speed = 392 / 7 = 56.0 hours
3. The first car will be 392 km ahead after 56.0 hours
