This question: 1 point(s) possible FX Two boats leave a dock at the same time. One boat travels south at 20 mi / hr and the other travels east at 48 mi / hr. After half an hour, how fast is the distance B between the boats increasing? . . .. . Let x be the distance the eastbound boat has traveled, y be the distance the southbound boat has traveled, and z be the distance between the boats. Write an equation that relates x, y, and z. R) till j Differentiate both sides of the equation found in the previous step with respect to t. er dz dx aster C dt dt it Card (Do not simplify.) by TD After half an hour, the distance between the boats is increasing at mi / hr. expenses Next
