Answer:

  • It took him 3 minutes to get to Lexington.

Explanation:

Using equations, let's solve. In the problem, it said that he ran at 200 meters per minute.

  • 200 meters = 1 minute
  • => 400 meters = 2 minute

Then, it said that "After 400m, he is tired and immediately slows to a rate of 100 meters per minute."

  • => 100 meters = 1 minute
  • 400 meters + 100 meters = 2 minute + 1 minute
  • => 500 meters = 3 minutes

Hence, it took him 3 minutes to get to Lexington.

Hoped this helped.
