She burns 250 by herself and she burns 3 times as many with her sister.
Multiply the calories by herself by 3:
250 x 3 = 750
Now you need to multiply that by the number of hours.
The formula is a. t[c(h)] = 750h
X+y=30
2x-3y=5
y=30-x
2x-3(30-x)=30
2x-90+3x=30
5x=120
x=24
y=30-x
y=30-24
y=6
The positive difference between the two numbers is 18.
