Calculate the average speed of segment BC.
The first thing we learned about in our Physics unit this semester was how to calculate speed. We are going to practice calculating speed using a distance time graph.
The magic triangle helps you determine which formula to use, depending on what you are solving for. Just cover up the letter of the variable you are trying to solve for, and you will have the formula to use. Calculate the speed of line segment CD. Since you are calculating speed, you cover up the S on the magic triangle, and the formula is S=D/T.
It can help to draw lines to show where the object started moving and stopped moving during segment CD.
We are calculating speed, so we use S=D/T
S=9/4, S= 2.25 m/s

Calculate the average speed of segment BC.
.4 m/s
.7 m/s
.16 m/s
2.5 m/s
To calculate the average speed of segment BC, we need to use the formula:
average speed = total distance / total time
From the given information, we do not have the total distance or the total time. Therefore, we cannot calculate the average speed of segment BC.
