A track shown above, there is a rectangle in the centre and 2 sides at the each end of the tracks are semi-circles. If the rectangle’s length is 600 feet and the diameter of the semi-circles is 400 feet, and also 40 trees are plant evenly along the track’s end, what is the distance between 2 consecutive trees, approximately, in feet?

A. 30

B. 40

C. 50

D. 60

E. 80

-> 600+600+2π200=about 2,400 and 2,400/40=60.

Thus, D is the answer.

Hello

MathRevolution,

I have a doubt - it is listed that "2 sides at the each end of the tracks are semi-circles" and "40 trees are plant (ed) evenly along the track’s end"

Aren't the trees planted along

along the semicircle since that is the end?

If the question were that "40 trees are plant (ed) evenly along the track" then considering both the length along with circumference of two semi-circle makes sense to me.

Please help to clarify

MathRevolution, I think have the same question as

warriorguy, but in case he is referring to a single semicircle, which would make sense given the prompt's singular "the end".....

I'll ask further: I interpreted "trees are plant[ed] evenly along the track's end" to mean "planted around the perimeter/circumference of

both semicircles."

If

warriorguy has caught a typo, does "the end" consist of just one semicircle, or both? Thanks in advance.
