Is part of your question missing? Or is there a typo? Is it supposed to read '..covers the distance in 36 sec.'?

Distance = Rate * Time

Or, for our purposes,

Rate = Distance/Time

From the rate, m/s, you should be able to figure out the ' beats by. '

Speed = Distance/ Time

Use this formula to get answer for your question
