Kevin's wife picks him up after work every day at 5:30 pm. One day, he leaves at 4:58 pm, and starts walking home. She pick him up along the way , and when they get home, he notices that they saved four minutes. How long did Kevin walk? :)

To answer this question, we can break it down into steps:

Step 1: Calculate the difference in time between 5:30 pm and 4:58 pm.

To calculate the time difference, we need to subtract the starting time (4:58 pm) from the pick-up time (5:30 pm). To ensure accurate calculations, let's convert the times to a common format, such as total minutes.

4:58 pm can be converted to 298 minutes (4 hours multiplied by 60 minutes, plus 58 minutes).
5:30 pm can be converted to 330 minutes (5 hours multiplied by 60 minutes, plus 30 minutes).

Now, we subtract 298 minutes from 330 minutes:
330 minutes - 298 minutes = 32 minutes.

So, the difference in time is 32 minutes.

Step 2: Determine the time Kevin saved.

The question states that by walking home, Kevin and his wife saved four minutes. From this, we can infer that the amount of time it normally takes Kevin's wife to drive to their meeting point is four minutes.

Therefore, the time Kevin saved by starting to walk early is four minutes.

Step 3: Calculate how long Kevin walked.

To find out how long Kevin walked, we need to subtract the time Kevin saved (four minutes) from the time difference (32 minutes).

32 minutes - 4 minutes = 28 minutes.

Therefore, Kevin walked for 28 minutes.
