Math Problem Statement
Two hikers leave their camp (P) at the same time. Hiker A walks due east for 9 km and Hiker B walks due south for 9.5 km. a) How far apart are the two hikers at this point, correct to 2 decimal places? b) What is the bearing of Hiker A from Hiker B, correct to the nearest degree? c) What is the bearing of Hiker B from Hiker A, correct to the nearest degree? d) Suppose Hiker B now heads off on a true bearing of 150 ° for 11 km. How far east would he be from his starting point? Page 7
