Motion

How could you use a tape measure and a timer to work out speed?

• Use the tape measure to measure speed and the timer to measure time and do distance / time

• Use the tape measure to measure distance and the timer to measure speed and do distance / time

• Use the tape measure to measure distance and the timer to measure time and do distance / time

• Use the tape measure to measure distance and the timer to measure time and do distance x time
