how do you set this up?

Question

Benjamin loves to hike in the White Mountains of New Hampshire. It takes him
   3

4 _

   4
hr to hike from the Pinkham Notch Visitor Center to the summit of Mt. Washington. If the round trip usually takes 9 hr, how long does it take for the return trip?

Answer 1

This is just a subtraction problem to check your ability to preform fraction subtraction.

Just try to write the given first, that is:

One way is 4 3/4 hour

Both ways 9 hour

Then returning back trip will take 4 1/4 hour

( 9 - 4 3/4 = 4 1/4 )

I noticed that the question mentioned names to make the word problem more realistic, that is all!
