For average speed, we divide the total distance covered by the total time taken.
After doing that, you will see that Jane has the lowest average speed.
The reaction is an unbalanced redox reaction hence, the reaction can be balanced by using the half-reaction method.
<h3>What is a redox reaction?</h3>
The term redox reaction refers to the reactionnin which electrons are transferred hence one specie is oxidized while the other specie is reduced.
Looking at the reation as shown, we can see that the reaction is an unbalanced redox reaction hence, the reaction can be balanced by using the half-reaction method.
