A person walks 8.4522x10^1 m East, then turns around and walks 7.8409x10^1 m West. The total time to walk this distance was 8.7343x10^2 s. What is the speed of the walker, expressed to 3 significant figures?

Answered by TutorCat
Speed is scalar! therefore, it has magnitude, but no direction.

Add the two distances and divide by time!
