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:
A) (1, 7) Doesn't
B) (0, 4) Doesn't
C) (2, –2) Doesn't
D) (3, –5) DOES
All the steps are right at the exception of line 7 (and onwards)
line 6 : 6x = 42 (it's right). Now divide both sides by 6:
line 7 should be: 6x/6 = 42/6
line 8 should be: x = 7.
200 and 150 because 25% of 200 is 50 so subtract 50 from 200 because it is supposed to be 25% smaller
