Speed time graph of two cars A and B approaching towards each other is shown in figure. Initial distance between them is 60 m. The two cars will cross each other after time (in seconds):
Two cars A and B are placed 100 km from each other. If they start for each other at the same time they meet in 1 hour. If they start running in the same direction, the distance between them in one hour is 80km. What is the speed of car A in km/h?
