Awesome! To get Jerry's speed, just divide the distance he covers by the time he takes. So, if you divide \(50 \, \mathrm{metres}\) by \(10 \, \mathrm{seconds}\), you get \(5 \, \mathrm{metres \, per \, second}\). Metres per second is abbreviated to \(\mathrm{m/s}\). So, Jerry's speed is \(5 \, \mathrm{m/s}\).
Jerry is driving a car. The car will have a speedometer that will measure its speed. During the ten seconds of the travel, what will the speedometer read?
  • It reads \(5 \, \mathrm{m/s}\) all the time because that is Jerry's speed
  • It doesn't have to read \(5 \, \mathrm{m/s}\) all the time
