The runner's average speed in meter per seconds (m/s) is equal to 6.71.
Given the following data:
To calculate the runner's average speed in meter per seconds (m/s):
What is speed?
Speed can be defined as the distance covered by an object per unit of time. Thus, speed can be measured in meter per seconds (m/s).
Mathematically, speed is given by this formula;
[tex]Speed = \frac{distance}{time}[/tex]
In this exercise, we would convert the value of distance in miles to meters. Also, we would convert the value of time in minutes to seconds.
Conversion:
1 mile = 1609.34 meters.
4 minutes = [tex]60\times4[/tex] = 240 seconds.
Substituting the given parameters into the formula, we have;
[tex]Speed = \frac{1609.34}{240}[/tex]
Speed = 6.71 m/s.
