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, and has a slope of (1:250) it is km away. Enter only the numeric value of the distance.

Explanation:

Apply the formula

  Where Z is the Distance of the warm front

              D is the Estimated distance

              S is the slope

 From the question the objective is to obtain distance of the warm front

             and we are given the estimated distance as 6 Km

             and slope S as {1:250} =

                                Substituting
