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 80 km apart from each other on a highway. A car starts from A and another from B at the same time. If they move in the same direction they meet in 8 hours , and if they move in opposite direction, they meet in 1 hour and 20 minutes respectively. Find the speed of the cars.

A and B are two points of 150 km apart on a highway. A car starts from A and another from B at the same time. If they move in the same direction, they meet in 15 hours, but if they move in opposite direction, they meet in one hour. Find their speeds.

Form the pair of linear equations in the following problems and find their solutions (if they exist) by any algebraic method :- Points A and B are 70 km apart on a highway. A carstarts from A and another car starts from B simultaneously. If they travel in the same direction, they meet in 7 hours, but if they travel towards each other, they meet in one hour. Find the speed of two cars.

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 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 ?

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 a highway. One car starts from A and another from Bat 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?

A car travels 90 km in 2 1/2 hour. Find the distance covered in 2 hours with the same speed.

There is a circular path around a sports field. Sonia takes 18 minutes to drive one round of the field, while Ravi takes 12 minutes for the same. Suppose they both start at the same point and at the same time and go in the same direction. After how many minutes will they meet again at the starting point?

A and B are persons standing in corner square as shown in the figure. They start to move on same time with equal speed, of A can move in East or South diretion and B can move in North or West diretion. If in each step they reach in next square and their choice of direction are equlity. If it is given that A and B meet in shaded region, then the probability that they have met in the top most shaded square, is

The perpendicular from the origin to a lne meet at the point (-2, 9), find the equation of the line.
