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 $$5 \, \mathrm{m/s}$$.
• 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
