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 kilometer overhead.
1. If a warm front is approaching from the south, find about how far away is it (assuming a slope of 1:200)?
2. If it is moving toward you at an average warm-front speed of about 10 knots, find how long will it take before it passes your area?
