An electric skateboarder is travelling west on a path along the river at 5m/s. Å brisk walker on the other side of the riverbank is walking east along a path at 3m/s. The two paths are 40m apart. The skateboarder is initially 600m east of the walker. After 60 seconds, how fast is the distance between the skateboarder and the walker changing?
