Question

Larry leaves home at 9:06 and runs at constant speed to the lamppost seen in (Figure 1). He reaches the lamppost at 9:09, immediately turns, and runs to the tree. Larry arrives at the tree at 9:15. What is Larry's average velocity, in m/min

, during each of these two intervals.

Answer 1

Larry's average velocity during each of the two intervals is 0.17 km/min.

Step-by-step explanation:

In order to find Larry's average velocity, we need to determine the total distance traveled and the time taken for each interval. From the given information, Larry runs from home to the lamppost in 3 minutes, covering a distance of 0.5 km. The average velocity can be calculated as:

Average velocity = Total distance traveled / Total time taken

Average velocity from home to the lamppost = 0.5 km / 3 minutes = 0.17 km/min

Similarly, Larry runs from the lamppost to the tree in 6 minutes, covering a distance of 1 km. The average velocity for this interval can be calculated as:

Average velocity from the lamppost to the tree = 1 km / 6 minutes = 0.17 km/min

Therefore, Larry's average velocity during each of the two intervals is 0.17 km/min.
