Two cars A and B are traveling at the speed of 30 kph and 40 kph respectively on two different roads making an angle of 30 deg with each other.

Two cars A and B are traveling at the speed of 30 kph and 40 kph respectively on two different roads making an angle of 30° with each other. Car A is located 200 m from the intersection of the roads at the instant car B is 400 m from the intersection. After a lapse of 5 minutes, how far is car A from car B in meters.

Solve for D in the given partial fraction:$$ \dfrac{4x^2 + 7x + 8}{x(x + 2)^3} = \dfrac{A}{x} + \dfrac{B}{x + 2} + \dfrac{C}{(x + 2)^2} + \dfrac{D}{(x + 2)^3} $$
