A jet travels at 800 miles west at 310 mi/hr and then travels at 250 mi/h east for 3 hrs. What is the average velocity for the trip?
Homework Answers
Given that the jet traveled 800 miles west at 310 mi/hr and then traveled at 250 mi/h east for 3 hrs.
Consider the 1st part
Speed =Distance/Time
==================
Consider the second part
Speed =Distance/Time
====================
Since we are considering average velocity direction is important
Take west as positeive and east negative
Average velocity = Total displacement /Total time
