If Winnie walks 2 miles in 30 minutes, 30 minutes is half an hour so for 1 hour which is 60 minutes, she can walk 4 miles, 90 minutes she can walk 6 and for 120 minutes which is 2 hours she can walk 8.
So all I did was multiply 2 by 4 and got 8. The number 4 came from the thought that 2 hours have 4 sets of 30 minutes

Answer:
Percentage=33.33%
Step-by-step explanation:
Total number of students=Number of 8th grader+others who went on trip
where;
Total number of students=60
Number of 8th graders=20
Others who went on trip=x
replacing;
60=20+x
x=(60-20)
x=40
Others who went on trip=x=40
Ratio of number of eighth graders to the number of everyone who went on the trip is;
Eighth graders who went=20 students
Everyone who went including the eighth graders=60
20/60==1/3
(1/3)×100=33.33%
Percentage=33.33%
So the problem is asking you to combine equations, in this case the Y factor will cancel out so you will be left with the X factor and the total after you add both of the totals together,
6x-4y=16
5x+4y=6
6x-5x=x
16+6=22
x=22
