A yacht is being tracked along a straight path using a radar. At the instant shown, the yacht is d = 281 m north of the radar, and r = 444 m away from the radar, moving eastwards at 5.9 m/s as shown in the diagram below. Calculate how fast the distance between the yacht and the radar is increasing. Express your answer in units of m/s to two significant figures, but do not include the units in your answer.
