1. Nuri wants to determine the average distance she travels each day in her car. She records the odometer reading each morning for a week in the following table: Day: 1 2 3 4 5 6 7 Odometer (mi) : 10,150 10,211 10,424 10,769 10,884 11,155 11,477

The average is the total number of miles run dived by the number of days.

The total number of miles is the difference of the last reading (11,477) less the initial reading (10,150) = 11,477 - 10,150 = 1,327 miles.

The number of days is 7.

The the average is:

average = number of miles run / number of days = 1,327 miles / 7 days = 189,6 miles / day.

Answer: 189,6 miles / day.
