One travels north at 24 mph, the other travels east at 10 mph. Determine the rate at which the distance be tween them is changing after 2 hours of riding. 1. rate = 28 mph 2. rate = 26 mph 3. rate = 29 mph 4. rate = 30 mph 5. rate = 27 mph 002 10.0 points A point is moving on the graph of xy = 3. When the point is at (4 , 3 4 ), its xcoordinate is increasing at a rate of 1 units per second. What is the speed of the ycoordinate at that moment and in which direction is it mov ing? 1. speed = 35 16 units/sec, increasing y 2. speed = 35 16 units/sec, increasing y 3. speed = 19 16 units/sec, increasing y 4. speed = 19 16 units/sec, decreasing y 5. speed = 3 16 units/sec, decreasing y 6. speed = 3 16...
