A salesperson drove 238, 159, 87, 163, and 198 miles (mi) on a 5-day
trip. What was the mean number of miles driven per day?
From what I remember the mean is another way of saying: what was the average number of mile driven per day?
If that's the case:
238+159+87+163+198=845
845 divided by 5 = 169 miles driven per day
