SUMMARY
The problem requires a race car driver to maintain an average speed of 180 km/h over 4 laps to qualify. Due to engine issues, the car only averages 150 km/h for the first 2 laps. To determine the necessary speed for the last 2 laps, one must calculate the total time for 4 laps at 180 km/h, the time for the first 2 laps at 150 km/h, and then derive the required speed for the final laps using the equation v = d/t.
