My teacher gave me problems to do related to Optimization. Well, I did one of the questions, using basic geometry, and didn't involve calc at all. I am 100% I am wrong. Can you please tell me how to do this problem.(adsbygoogle = window.adsbygoogle || []).push({});

John wants to get to the bus stop as quickly as possible. The bus stop is across a grassy park, 2000 feet west and 600 feet north of her starting position. Jane can walk west along the edge of the park on the sidewalk at a speed of 6 ft/sec. She can also travel though the grass in the park, but only at the rate of 4 ft/sec. What path will get her to the bus stop the fastest?

The method i used was below to solve this problem

x = vt

2000 + 600 = 6t

t = 433.3333

I got 2088 below by using the phythoregeon theorm.

2088 = 4t

t = 522
