From a point marked as X in a swimming pool, which is circular in shape, two friends Jack and Straw start
swimming simultaneously at uniform speeds in opposite directions. The circumference of the pool is 100 metres. The
water inside the pool flows in the clockwise direction at a uniform speed. Jack swims along the water flow. The two
friends meet for the first time at a distance of 30 metres from point X in the clockwise direction. Straw reverses his
direction immediately after meeting with Jack for the first time. The time duration from the 1st meeting to the 2nd
meeting is 10 seconds. If the ratio of the speed of Jack to that of Straw is 2 : 5, then the speed at which water flows in
the pool is
