$$Average Speed=\frac{Total Distance}{Time_p}$$

$$Time_p=TimeTotal-ReactionTime$$

 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

$$Time_p=249.28-0.71=248.57 seconds$$

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

 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

$$Time_p=114.66-0.72=113.94 seconds$$

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