Two swimmers start a race. One who reaches the point `C` first on the other bank wins the race.`A` makes his strokes in a direction of `37^(0)` to the river flow with velocity `5km//hr` relative to water. `B` makes his strokes in a direction `127^(0)` to the river flow with same relative velocity.River is flowing with speed of `2km//hr` and is `100m` wide.speeds of `A` and `B` on the ground are `8km//hr` and `6km//hr` respectively.
