3.75 kimThe torpedo will be fired at an angle of 46.8 degrees east of North. If you substitute the angle to the equation t = 0.075h / cosx, where x is the computed angle and h is a constant 60 min / 1 hr, then the torpedo will hit the battleship in 0.66 min.
Therefore, the answer for a) 46.8 degrees East of North and b) 0.66 minutes
