Question

You own Everything's Coming Up Roses flower shop. Your employee makes 4 deliveries per hour. The distance between the shop and the first delivery is 12 1/3 miles. The distance between the next three deliveries is 8 3/4 miles; 17 2/8 miles; and 23 2/3 miles respectively. The distance from the final delivery to the shop is 10 5/10 miles. What is the average distance for all segments of this trip?

Answer 1

We have 4 deliveries ( 12 1/3 , 8 3/4, 17 2/8 and 23 2/3 miles ) and also the final delivery : 10 5/10 miles = 10 1/2 miles.
We have to add up all the deliveries and to divide the result by 5:
( 12 1/3 + 8 3/4 + 17 1/4 + 23 2/3 + 10 1/2 ) : 5 =
= 72 1/2 : 5 = 72.5 : 5 = 14.5 = 14 1/2
Answer: The average distance for all segments of this trip is 14 1/2 miles.
