Two boats `A` and `b` move away form a buoy anchored at the middle of a river along mutually perpendicular staight line. The boat `A` moves along the stream and the boat `B` across the river. After moving off an equal distance of `500` metre form the buoy both the voats returned to their original position. Find the ratio of the time taken by boat `A` to that taken by boat `B` if the velocity of ecah boat with respect to water is `20m//s` and the stream velocity si `10m//s`.
