$AverageSpeed={\frac {TotalDistance}{Time_{p}}}$

$Time_{p}=TimeTotal-ReactionTime$

Example 1

To get total time, you convert minutes to seconds. For example, a time of 4:09.28 minutes converts to 249.28 seconds. This is seen by:

1 minute=60 seconds

60(4)+9.28=249.28 seconds

To get average speed, determine distance and time you are using:

total distance: 400m

reaction time: 0.71 seconds

$Time_{p}=249.28-0.71=248.57seconds$

$AverageSpeed={\frac {400m}{248.57seconds}}=1.61m/s$

Example 2

To get total time, you convert minutes to seconds. For example, a time of 1:54.66 minutes converts to 114.66 seconds. This is seen by:

1 minute= 60 seconds

60(1)+54.66=114.66 seconds

To get average speed, determine distance and time you are using:

total distance: 200m

total time: 1:54.66=114.66 seconds

reaction time: 0.72 seconds

$Time_{p}=114.66-0.72=113.94seconds$

$AverageSpeed={\frac {200m}{113.94seconds}}=1.76m/s$
