    Given a tuple containing consecutive distance measurements between delivery checkpoints, calculate the combined distances of adjacent route segments by adding each pair of neighboring measurements. The resulting calculations will help determine optimal delivery zones by understanding the total distance covered in consecutive segments of the delivery route.
