10. You timed your endurance with a stopwatch and measured 32min 24sec overall without stopping the measurement inbetween for all 26 laps. You know, that your driver change lasted 2min 13sec (including extra-long lap for change) and you threw 7 cones. In addition one driver achieved an off-course. From the fastest team you got the corrected time 23min 2sec and from the slowest 35min 8sec. Calculate your endurance score! NOTE: There are no changes in course condition during the running.
