Can someone please explain how to solve this question as i know I need to use the Sine rule I just don't know how to apply it.
Mathematics: A cross country runner runs at 8km/h on a bearing of 150*T for 45 mins; then he changes direction to a bearing 053*E and runs 80 mins at a different speed until he is due east of the starting point.
a) How far was the second part of the run?
b) What was his speed for this section?
c) How far does he need to run to get back to the starting point?
