Lisa walked 8 km more than Tim. Lisa walked twice as far as Tim. How far did each walk?

Question

MattFat · Answer

T = 8 L = 16 
 we write out the given equations: L = T + 8 2T = L we substitute the 2nd into the 1st 2T = T + 8 T = 8 L = (8) + 8 L = 16

MattFat · Answer

Tim walked 8 km, while Lisa walked 16 km. We determined this by setting up equations for the distances based on the relationships given in the problem and solving them. By substituting one equation into another, we found the distances each person walked.
