You and a friend are both traveling from the seattle area. you start 38 miles east of seattle and travel east on interstate 80 at 62 miles per hour. your friend starts 20 miles south of seatle and travels south on interstate 5 at 65 miles per hour a. who would be farther from seattle in two hours and by how much? b. how many hours will it take for you and your friend to be the same distance from seattle?

A)

well, you started with 38 miles and are going 62mph, so every passing hour you're 62 miles farther, so say after "h" hours, you have gone 38 + 62h miles eastward.

your friend is going southward starting with 20 and going 65mph, so after "h" hours she's gone 20 + 65h miles then.

now in 2 hours, that's h = 2, so you've gone 38 + 62(2)  and she's gone 20 + 65(2), so check which is larger.

b)

well, when your and her are the same distance from Seattle, is when the miles covered by both are equal, when is that?  well
