<u>Given:</u>
Number of pages read by Jack = 40 per hour
Rate of reading by Dave =3/5 of a page in a minute
<u>To find:</u>
The person who reads faster and by how many minutes.
<u>Solution:</u>
If Dave reads 3/5 of a page in a minute then in an hour he would read,
(60 minutes = 1 hour)
pages in an hour
The difference between pages read by Jack and Dave is
Therefore, Jack reads faster than Dave by 4 pages.

Answer:
1/5 miles
Step-by-step explanation:
2/5 divided by 2 = 1/5
There is a not so well-known theorem that solves this problem.
The theorem is stated as follows:
"Each angle bisector of a triangle divides the opposite side into segments proportional in length to the adjacent sides" (Coxeter & Greitzer)
This means that for a triangle ABC, where angle A has a bisector AD such that D is on the side BC, then
BD/DC=AB/AC
Here either
BD/DC=6/5=AB/AC, where AB=6.9,
then we solve for AC=AB*5/6=5.75,
or
BD/DC=6/5=AB/AC, where AC=6.9,
then we solve for AB=AC*6/5=8.28
Hence, the longest and shortest possible lengths of the third side are
8.28 and 5.75 units respectively.
