Quizplus · Accepted Answer

The mean speed is the sum of all the speeds divided by the number of speeds. In this case, the mean speed is (181.1 + 202.2 + 190.1 + 201.4 + 191.3 + 201.4 + 192.2 + 201.2 + 193.2 + 201.2 + 194.5 + 199.2 + 196.0 + 196.2) / 14 = 2735.4 / 14 = 195.39. Rounded to the nearest tenth, the mean speed is 195.8 mph.
