The straight roads intersect at an angle of 60°. A bus on one road is 2 km away from the intersection and a car on tire other road is 3 km away from the intersection. Then, the direct distance between the two vehicles, is

Two cars get closer by 8 m every second while traveling in the opposite directions. They get closer by 0.8 m while traveling in the same directions. What are the speeds of the two cars ?

Two separated sources emit sinusoidal travelling waves but have the same wavelength lambda and are in phase at their respective sources . One travels a distance l_(1) to get to the observeration point while the other travels a distance l_(2) . The amplitude is minimum at the observation point , l_(1) - l_(2) is an

Places A and B are 100 km apart on a highway. One car starts from A and another from b at the same time. If the cars travel in the same direction at different speeds, they meet in 5 hours. If they travel towards each other, they meet in 1 hour. What are the speeds of the two cars

Two trains leave a railway station at the same time. The first train travels towards west and the second train towards north. The first train travels 5 km/hr faster than the second train. If after two hours they are 50 km apart find the average speed of each train.

Two motor boats A and B move from same point along a circle of radius 10 m in still water. The boats are so designed that they can move only with constant speeds. The boats A and B take 16 and 8 sec respectively to complete one circle in stationary water. Now water starts flowing at t=0 with a speed 4(m)/(s) in a fixed direction. Find the distance between the boats after t=8 sec.

A level flight olane flying at an altitude of 1024 ft with a speed of 240 ft/s is overtaking a motor boat travelling at 80 ft/s in the same direction as the plane. At what horizontal distance before the boat should a bag be dropped from the plane in order to hit the boat ? [ g = 32 " ft/s"^(2) ]
