Explain the all part of the given problem

Problem- You are a meteorologist. While taking present weather observations, you note that the sky is full of wispy cirrus clouds estimated to be about 6 km overhead.

Part A- If a warm front is approaching from the south, about how far away is it (assuming a slope of 1:200)?

Part B- If it is moving toward you at an average warm-front speed of about 10 knots, how long will it take before it passes your area?

I need help to describe the above problem.
