A runner runs around a circular track four times.

Their coach uses a stopwatch to record the times at the start of the run, after two laps, and at the end of the four laps. The readings from the stopwatch are:

  • At the start: 5.50 s
  • After two laps: 165.50 s
  • At the end of four laps: 325.50 s

What is the average time for one lap of the track?
