Considering the description above, Pierre's average speed for this race, in miles per hour, is measured as:
Given that Pierre's average speed is calculated in miles per hour;
Then, we divide his total mileage by his total time;
Therefore, the total number of miles Pierre covered is the distance from starting point S to finish line F;
=> This is depicted as "SF." (Total mileage);
Again, the total elapsed time from point S to point F is depicted as "t.F." (Total Time).
Hence, in this case, Pierre's average speed for this race, in miles per hour, is SF ÷ t.F. [Total mileage ÷ Total time]
