Question

You and a friend are both traveling from the seattle area. you start 38 miles east of seattle and travel east on interstate 90 at 62 miles per hour. your friend starts 20 miles south of seattle 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

Answer 1

East car distance from Seattle = 38 + 62x

South car distance from Seattle = 20 + 65x

Equation:

38+62x = 20+65x

18 = 3x

x = 6 hours
