is it at 1530 hours? Jack drives north at \( 80 \mathrm{~km} / \mathrm{h} \) for 2 hours. He then turns and drives east at the same speed for 3 hours. (a) To the nearest degree, what is Jack's true bearing from his original position? (b) If Jack could drive from his current position straight back to his starting position: (i) how far would he travel, to the nearest kilometre (ii) what true bearing should he follow?
