Use cross-multiplication:
4 mi/77mins=x mi/120mins
to solve would be 4 miles times 120 minutes divided by 77 minuntes to get unknown (x) miles.

first change 2h to min == 120 min. U have to use proportion o to that u do 4/77 === x/120. x is how many mi she will hike in 2 h or 120 min. cross multiply 77x == 480 divide 77 from both side so u get x by it self 480/77 === about 6.23

In 77 min hiked = 4 miles
120 minutes = (4/77)x120
= 6.23 miles (app)

4 Miles/77 Minutes = X Miles / 120 Minutes
Cross multiply and Divide:
4 * 120 / 77 = X
480 / 77 = X
6.23 Miles = X
Hope this helps.

first find the rate of travel
4mi / 77min = 0.051948 mi/min
then multiply the rate by the time hiked
0.051948mi/min x 120 min = 6.233 milies

4/77 = x/ 120
77x = 480
x = 6.2 (rounded to tenths)

4mi/77min=xmi/120min (2h=120min)
120x4=480
480/77=6.23
