Question

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

Answer 1

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.
