Soldiers are on a training mission on jungle survival. The squad travels from a temporary base (B) in a direction N 60º W to a swamp (S) and then S 40º W to a rest area (R) directly west of the base. The squad then returns the 8 direct miles from the rest area to the base. Find the distance from the base to the swamp, to the nearest tenth of a mile.

Harrison flies his plane from point A at a bearing of N 35º E, averaging 137 miles per hour for 4 hours to get to a local airport at point B. He then leaves that airport flying N 70º W averaging 134 miles per hour for 3 hours to arrive at another airport at point C. Find the direct distance from C to A to the nearest tenth of a mile.
