James and Henry are at the northwest corner of their business school's football field, which is a rectangle 300 ft long and 160 ft wide. James walks in a straight line directly to the southeast corner of the field. If Henry walks 180 ft down the west side of the field and then walks in a straight line directly to the southeast corner of the field, how many feet farther, to the neareast 10 ft, will Henry walk than James?
A. 20
B. 40
C. 80
D. 120
E. 140
The OA is B.
I know that I can determine the distance covered by James using the dimensions of the field and the Pythagoras's theorem, then
$$\sqrt{\left(300\right)^2+\left(160\right)^2}$$
But, I don't understand how can I determine the distance covered by Henry.
Experts, can you help assist me with this PS question, please? Thanks!
