An electric skateboarder is travelling west on a path along the river at 4m/s. A brisk walker on the other side of the riverbank is walking east along a path at 2m/s. The two paths are 40m apart. The skateboarder is initially 200m east of the walker. After 60 seconds, how fast is the distance between the skateboader and the walker changing?
