A swimmer crosses a river with minimum possible time 10 Second. And when he reaches the other end starts swimming in the direction towards the point from where he started swimming. Keeping the direction fixed the swimmer crosses the river in 15 sec. The speed of river flow and swimmer is constant. Find the ratio of speed of swimmer with respect to water and the speed of river flow.

From the top of a tower of height 10m, one fire is shot horizontally with a speed of 5 root3 m/s. Another fire is shot upwards at angle of 60^o with the horizontal at some interval of time with the same speed of 5 root3 m/s. The shots collide in air at a certain point. The time interval between the two fires is
