On one boundary of a swimming pool , there is a person at point A whose speed of running on group (boundary) is 10ms^(-1) , while that of swimming is 6ms^(-1) . He has to reach a point B in the swimming pool . The distance covered on the boundary so that the time required to reach the point B in the pool is minimum, is

How is water in a swimming pool kept free from germs ?

Two pipes of different diameters may be used to fill a swimming pool. The price with the larger diameter working alone can fill the swimming pool 1.25 times faster than the other pipe when it works alone. One hour after the larger pipe is opened, the smaller pipe is opened, and the swimming pool is filled 5 hours later. Which equation could be used to find the number of hours, x, it would take for the larger pipe to fill the pool working alone?

A swimming pool 70 m long, 44 m wide and 3 m deep is filled by water flowing from a pipe at the rate of 30,800 cm^(3) per second. The time taken to fill the swimming pool is:
