An aeroplane leaves an airport and flies due north at a speed of 1000 kmph. At the same time, another aeroplane leaves the same airport and flies due west at a speed of 1200 kmph. How far apart will the two planes be after 1 `(1)/(2)` hour ?

An aeroplane leaves an airpot and flies due north at a speed of 1,000 km per hour. At the same time, another aeroplane leaves the same airport and flies due west at a speed of 1,200 km per hour. How far apart will be the two planes after 1 1/2 hours?

An aeroplane leaves an airport and files due north at a speed of 1000 km per hour. At the same time, another aeroplane leaves the same airpot and flies due west at a speed of 1200 km per hour . How far apart will be the two planes after 1(1)/(2) hours ?

Form the pair of linear equations in the following problems and find their solutions (if they exist) by any algebraic method : Places A and B are 100 km apart on highway. One car starts from A and another form 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 ?

Places A and B are 160 km apart on a highway. One car starts from A and another from B at the same time. If they travel in the same direction they meet in 8 hours. But if they travel towards each other, they meet in 2 hours. Find the speed of each car. Let P and Q be the cars (1) starting from A and B respectively.

OA and OB are two roads enclosing an angle of 120^(@) .X and y start from 'O' at the same time. X travels along OA with a speed of (4km)/(hour) and Y travels along OB with a speed of (3km)/(hour) .The rate at which the shortest distance between X and Y is increasing after 1 hour is

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.

Sameera was driving a car with uniform speed of 60 kmph. Draw distance-time graph. From the graph find the distance travelled by Sameera in (i) (1)1/2 hours (ii) 2 hours (iii) (3)1/2 hours
