Two cars starf simultaneously from the same place and in same direction . The first car moves with a uniform speed of 10 km/h . The second car moves at a speed of 8km/hr in the first hour and then increases its speed by 0.5 km/hr in each succeeding hour . If both the cars move non stop , then how long will it take for the second car to overtake?
Points A and B are 90 km apart on a highway. A car starts from A and another from B at the same time. If they travel in the same direction they meet in 9 hours and if they travel in opposite directions they meet in 97 hours. Speed of car starting from point A is:
Two cars A and B are moving in same direction with a speed of 30km per hr. They are separated from each other by 5 km. Third car moving in the opposite direction meets the two cars after an interval of 4 mins. The speed of third car is ? ( use relative velocity to solve the problem)
1. 30km per hr
2. 25km per hr
3. 40km per hr
4. 45km per hr
