Running:
125 x 3 = 375
Walking:
85 x 3 = 255
375 - 255 = 120, so 120 more by running.

Walking.
1 mile = 85 calories
85 x 3 miles = 255 calories
Running.
1 mile = 125 calories
125 x 3 miles = 375 calories
375 - 255 = 120 more calories.

walking 3 miles will burn 85*3=255 calories
running 3 miles will burn 125*3=375 calories.
So subtract 255 from 375 and you get 125 calories more burned by running 3 miles than walking.

Well, you know that since she burns 125 calories in an hour while running, she will burn 375 calories in 3 hours.
You also know that since she burns 85 calories while walking an hour, she will burn 255 calories in 3 hours.
Subtract 375-85
Get the difference, and that's your answer.
