Answers with Solutions (1-4):
1. (1): total distance travelled by B at the end of 8th hour = 210 km and by A =185 km,
Distance between A and B = 25 km.
2. (2): Average speed = Total distance / Total time = 11/25 = 22kmph
3. (4): It is maximum at the end of 5th hour.
4. (3): A’s speed during first 5 hrs = 22 kmph
A’s speed during last 5 hours =125/5 = 25kmph.
Ratio: 22:25
