If a car is traveling at an average speed of 60 kilometers per hour, how long does it take to travel 12 kilometers?

• 0.2 hour

• 0.5 hour

• 0. 0.7 hour

• 5.0 hours

What is the difference between speed and velocity?

• Velocity is always greater than zero, but speed can be greater or less than zero.

• Speed is always greater than zero, but velocity can be greater or less than zero.

• Speed includes an object's direction, and velocity does not.

• Velocity includes an object's direction, and speed does not.

The table shows the distances and times it took for Mary, Jake, Tina, and Jose to race across their school campus to their science class. Each student took a different path causing their distances traveled to vary. Use the information in the table to determine who had the slowest speed.

• Tina

• Jose

• Jake

• Mary
