Getting home early 10 minutes means that the car is driving less 10 minutes.
65,438+00 minutes less walking is because you don't have to drive to work in Iraq.
Therefore, the distance this person has traveled is *2 less (usually, he has to drive to the office and then drive back).
In other words, when the car was about to drive to the office in 5 minutes, it met this man.
This time is 5 minutes before 5 o'clock, which is 4: 55.
So the man walked for 55 minutes.
