Answer:
The latest time that chris can leave to drive to work and arrive by 8:00 = 7:50
Step-by-step explanation:
It takes Chris 30 minutes to walk to work.
Time taken by walking = 30 minutes.
If he drives, it takes him 1/3 of that time
[tex]\texttt{Time taken by walking = }\frac{1}{3}\times 30=10minutes[/tex]
Now he need to reach the work by 8:00, we need to find when he need to leave home.
It will take 10 minutes, so we need to reduce 10 minutes from 8:00,
8:00 - 10 minutes = 7:50
The latest time that chris can leave to drive to work and arrive by 8:00 = 7:50
