So lets say the distance one boy travels is 'x', you can set up an equation like this:
x + x + 1 = 7
2x +1 = 7
2x = 6
x = 3
So one boy walks 3 miles in one hour, and the other walks 4 miles in one hour.
Therefore, their speeds are 3 miles per hour and 4 miles per hour respectively.
You need the greatest common factor of the two numbers. In this case, 20 is a factor of 100, meaning that Angie can make 20 groups, each with 5 cookies and 1 brownie.
