Question

A ship is headed due north at a constant 15 miles per hour. Because of the ocean current, the true course of the ship is 12°. If the currents are a constant 12 miles per hour, in what direction are the currents running? Apply the rules regarding the use of significant digits after all computations are complete. a. S 3º E b. N 22° E, N 3° E OC S 20° E d. S 27° E, N 24°E e. N 27° E. S 3º E

Answer 1

Then, according to the problem M ^ VB -1 E S { wil A = where ship is travelling at 15 milelhor = Speed of ocean, using since rude in above triangle- 15 12 IS Sin12 Sino Sino = Is sin12 O~150 Alence angle of ocean current 0 +12°N 27° H-E 2 option (e) is correct.
