Question 143923: A salamander scurries 10 inches along a straight path, then stops and rests. After catching its breath, it scurries (1/3) of its previous distance, continuing along its straight path before stopping to rest again. Tne salamander continues this pattern of travel along a straight path, moving (1/3) of the previous distance each time. Which expression will give the total distance the salamander has traveled after n moves?
A. 10 + (1/3)(10) + (1/3)^2(10) + ... + (1/3)^n-1(10)
B. 10 + (1/3)(10) + (1/3)^2(10) + ... + (1/3)^n(10)
C. 10(1/3)^n
D. 10(1/3)^n-1 Answer by stanbon(75887) (Show Source):
