Concept explainers
To translate: each problem into an equation and to find the distance walked by Time and Lisa each.
Answer to Problem 7P
Required equation :
Tim walked = 8 km and Lisa walked = 16 km.
Explanation of Solution
Given information:
Lisa walked 8 km more than Tim and she walked twice as far as Tim.
Calculation:
Let Tim walked=
According to first condition
Lisa walked (8 km more than Tim)
Now according to second condition
Lisa walks (twice as far as Tim)
Both conditions must be equal
Therefore, required equation would be:
Let us solve it for x now.
Subtracting x on both sides
Therefore, Tim walked = 8 km and Lisa walked
