A runner crossed the 1 mile marker of a race running at a speed of 9 miles per hour. She crossed the finish line running at a speed of 9.8 miles per hour. Did the runner change her velocity?

• Yes

• No

The Hummer is driving along at 2 m/s. Suddenly, the driver floors it for 5 seconds until the Hummer reaches a speed of 12 m/s. At what rate did the Hummer accelerate?

• 2.8 m/s

• 2 m/s

• 2 m/s²

• 2.8 m/s²

Answer explanation
