Answer: 33.33 minutes longer.
Step-by-step explanation :
We need to remember the following formula:
Where "t" is the time, "d" is the distance and "V" is the speed.
We know that she runs approximately 5.4 miles per hour, then:
Since she plans to run 9 miles on Tuesday, her run's time on Tuesday will be:
Making the conversion from hours to minutes, we get:
Since she plans to run 12 miles on Thursday, her run's time on that day will be:
Making the conversion from hours to minutes, we get:
Finally in order to find how many longer will her run be on Thursday compared to Tuesday, we need to make the following subtraction:
(22 - 3) / (4 +1) = 19/5
slope = 19/5
