This problem involves a limit and the greatest integer function. my current guess is b. 1/3.5. i plugged 3.5 in for x. my numerator became 1.5, but i rounded down to 1 because it is the greatest integer function and ended up with 2/7 or 1/3.5

the answer is 375 miles

\3. yes the presentation (i.e. odd numbers being written as differences of two squares) is possible for all odd natural number however the presentation may not be unique. for example,  57=112−82=292−28257=112−82=292−282.

\4. 2 can't be written as a difference of two squares because 4-1=3 and 1-1=0 and the difference of squares grows to integers larger that 3.

can i get some in proving questions 1 and 2?
