Arunner wants to run 14.1 km. she knows that her running pace is 7.4 mi/h how many minutes must she run? use 7.4mi/h as a conversation factor between distance and time

time = 71.034 minutes

Explanation:
First, we will convert the km into miles.
We know that one kilometer is equal to 0.621371 miles
Therefore,
14.1 km = 14.1 * 0.621371 = 8.7613311 miles
Now, the equation that relates the velocity (pace), distance and time is:
velocity = distance / time
We are given that:
velocity = 7.4 mi/hr
distance = 8.7613311 miles
Substitute with the givens in the above equation to get the time as follows:
velocity = distance / time
7.4 = 8.7613311 / time 
time = 8.7613311 / 7.4
time = 1.1839 hours
Converting this to minutes, we will find that:
time = 1.1839 hours = 1.1839 * 60 = 71.034 minutes

Hope this helps :)
