A race car driver must average 200.0 km/h over the course of a time trial lasting ten laps. If the first nine laps were done at 198.0 km/h , what average speed must be maintained for the last lap?
Avg Speed=Distance traveled/Time
218 km/h, I averaged the first 9 laps at 198 and plugged the speed for the tenth lap in until I got an average speed of 200 km/h
