Question

Two cars leave at the same time at an initial position. One car traveling at the direction of N 23 deg E at a speed of 11 mph, and the second car travelling at the direction of S 67 deg E at 15 mph. Calculate the (a) bearing from the 1st car to the 2nd car after 1 hour of travel and (b) the triangular area it creates in square meter.

Area of the Triangles are denoted by the following formulas:
1. Basic Formula,
A = 12 * base * height, where base is known and height is
perpendicular to the base.
2. 2 sides and an included angle, A = 12 * a * b * sin 4, where a and b are two known
sides and 4 is an included angle of the two known sides.
3. Hero's Formula, A = √s(s — a)(s — b)(s — c), where S = ½ (a+b+c), where a, b
and c are the three known sides of the triangle.
