SUMMARY

The discussion focuses on a related rates problem involving two individuals walking in perpendicular directions. A man walks north at 4 ft/s, while a woman starts walking south at 5 ft/s from a point 500 ft east of the man's starting position. After 15 minutes of the woman's movement, the rate at which they are moving apart is calculated to be 8.99 ft/s, derived from the equation yielding 837 divided by the square root of 8674.

This is a related rate problem.

A man starts walking north at 4 ft/s from a point P. Five minutes later a woman starts walking south at 5 ft/s from a point 500 ft due east of P. At what rate are the people moving apart 15 min after the woman starts walking?

I'm just trying to interpret it into the numbers and drawing a triangle. But I don't get a right equations for it.


the answer is 837/ sqaure root of 8674 which is 8.99 ft/s

Thank you so much.:smile:
