You can put this solution on YOUR website! Peter is three times as old as Will. When Will will be twice as old now, Peter will be 72 years old. How old is Peter?
Let w = age of Will
3w = age of Peter
w years from now, Will will be twice as old now
Also, w years from now, Peter will be 72 years old
3w + w = 72
4w = 72
w = 18
3w = 3(18) = 54
Peter is 54 years old
