Three scouts went on a three day trip. The second day went 4 km more than the first day. The third day went two times less than the first day. They went along 54 km. How many kilometers went every day together?


a =  20 km
b =  24 km
c =  10 km


b = 4+a
c = a/2
a+b+c = 54

a-b = -4
a-2c = 0
a+b+c = 54

a = 20
b = 24
c = 10
