By setting up a system of equations, we find that Tim walked 8 km and Lisa walked 16 km, as Lisa walked twice the distance of Tim and 8 km more.
The question describes a problem where Lisa walked 8 km more than Tim and that she walked twice as far as Tim. To solve this problem, we can set up a system of equations based on the information provided:
Let x represent the distance Tim walked.
Therefore, Lisa walked 2x (since Lisa walked twice as far as Tim).
It is also given that Lisa walked 8 km more than Tim, so we can express this as 2x = x + 8.
Now, we solve for x:
2x = x + 8
2x - x = 8 (Subtract x from both sides of the equation)
x = 8 (This is the distance Tim walked)
To find the distance Lisa walked, we substitute x into 2x: 2(8) = 16 km (This is the distance Lisa walked)
So, Tim walked 8 km and Lisa walked 16 km.
Tim walked 8 km while Lisa walked 16 km. This is concluded from the conditions given where Lisa walked 8 km more than Tim and also twice as far as him. By setting up equations based on the distances, we solved for each person's distance walked.
