• Multiply them.

• Ignore the smaller displacement.

Fill in the Blank

Speed is the distance an object travels per unit of ___.

Multiple Choice

Which of the following is the correct equation for calculating speed?

• speed = distance × time

• speed = distance / time

• speed = time / distance

• speed = distance + time

Multiple Select

Select all statements that are true about constant speed.

• A car traveling at constant speed does not change its speed.

• You can calculate constant speed by dividing distance by time.

• Constant speed means the speed is always increasing.
