Greyson lives 500 meters north of the highway i-287. the harding twp library is 1800 meters south of highway i-287 on sand spring road. if greyson walks at a casual 1.4 m/s from the library to his house, how long would it take?

1642.86 seconds

Explanation:

Constant Speed Motion

If an object is moving in a constant direction and travels same distances x in same times t, it's speed is constant and can be computed as

The time taken to travel x is computed by

We know Greyson must walk 500 meters to reach the highway and then 1800 meters to reach The Harding Twp Library. The total distance is 2300 meters. It's done with a constant speed of 1.4 m/s, so the time taken to get there will be

It's equivalent to 1642.86/60, approximately 27 minutes of walk

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
