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 kilometers (km) overhead.If a warm front is approaching from the south, has a slope of 1:300 and is moving toward you at an average warm-front speed of about 3.1 km/hour, how long will it take before it passes your area?Enter only the numeric value of the number of hours to one decimal place( e.g. 56.74 would be entered as 56.7)
