The diagram shows a pendulum that oscillates between P and Q.

Which method is used to find the average period of oscillation for the pendulum?

• Measure the time it takes to swing from P to Q.

• Measure the time it takes to swing from P to Q to P 10 times and divide that time by 10.

• Measure the time it takes to swing from P to Q to P 10 times and multiply that time by 10.

• Measure the time it takes to swing from Q to P.

A car moves through a measured distance s in a known time t. What is the correct equation used to calculate the average speed v of the car?
