The average speed is 75 Km per hour. Remember the equation for speed is Speed = Distance divided by Time
<u>Answer:</u> The equation is given below.
<u>Explanation:</u>
Single replacement reactions are the chemical reactions in which more reactive metal displaces a less reactive metal from its chemical reaction. General equation for these reactions is given by the equation:

Metal A is more reactive than metal B.
The reactivity of metals is judged with the help of reactivity series. In this series, the metals lying above are more reactive than the metals which lie below in the series.
For the reaction of solid lithium metal and nitric acid, the equation follows:

This is a type of single replacement reaction because Lithium (more reactive metal) is replacing Hydrogen (less reactive metal) from the chemical reaction.

Periodic table!
The periodic table organizes elements by their chemical properties (mainly through vertical columns known as groups) and increasing atomic number.
