that there is an "L" (for low pressure) at the center of the cyclonic system where the fronts are joined. Use a ruler and the scale at the bottom of the map to measure the distance due east from the "L" to the Atlantic coast, and solve this problem: If the storm is traveling due east at 40 kilometers per hour, how many hours will it take for the low pressure center reach the Atlantic coast? Solve using measured distance in kilometers divided by 40
