C. What is the horizontal distance from A to B measured along a straight line in ft? (Hint: Measure the distance from A to B using a metric ruler on the map, and then use your measurement of how many mm on the map equal 1000 ft in the field to find the answer using proportions.) Show your work. ft D. What is the average gradient (elevation change divided by horizontal distance, both expressed in ft) along a straight line from A to B? Show your work. E. In fact, it gets much steeper between X and Y along the slope to B. What is the gradient between X and Y?
