## Homework Statement

A whale swims due east for a distance of 8.0 km in a time of 2.50 hours. It then turns around and moves west for 2.0 km on a time of 0.50 h. It turns around again and heads 4.0 km due east in a time of 1.00h.

## Homework Equations

a. What is the total distance traveled by the whale?

b.

**What is the total displacement?**

c. Calculate the average speed for the entire trip.

d.

**Calculate the average velocity for the entire trip.**

## The Attempt at a Solution

I only got a and c correct, for a I put 14 Km and for c I put 3.5 km/ hr. I tried to do the question again and I drew out the whale swimming, and guessed that the displacement is 8 Km. This was a previous test, and the teacher didn't go over it! I'm trying to study for my exam ;). Thanks.
