Which interval contains the median lap time? An indoor running track is 200 meters in length. During a
3,000-meter race, runners must complete 15 laps of the
track. An electronic timing device records the time it
takes each runner to complete a lap for every lap in the
race. These are called lap times. The histogram below
displays the lap times for Stefano, a runner in the 3,000-
meter race.
