Hello,

A Land cruiser drives east from point A at 40 kph. Another car Ford Expedition, starting from B at the same time , drives northwest $30^\circ$ towards A at 60 kph. B is 40 km from A.

How fast in kph is the distance between two cars changing after 47 minutes?

Solution:-

My attempt: I want to use here sine law and cosine law. The computations are somewhat complicated and requires thorough thinking. I am trying to answer this question but it will take some time.

Meanwhile, if any member knowing the correct answer to this question , may reply with correct answer.
