Speed = distance / time
If you input your numbers into this equation you will be able to find the cyclists average speed
1 W = 1 J/s
Watt<span> is the unit of measure for power .
</span><span>
</span>Joule is the unit of measure for the energy and the second is the unit of measure for time.
The equation is
s= d/t
In this case you would have to write it out as:
s= 20/5
Speed = 4
