A company produces computers with 7 different speeds, and the ratio of each speed to the next one is a fixed ratio. If the fastest computer is 5.4 GHz, while slowest speed is 0.2 GHz, what is the speed of the second slowest computer? Choose the correct choice from the following:
A) (3^1/2) (0.2)
B) (27^1/7) (0.2)
C) (5.2/7) + 0.2
D) (0.2)^2
E) 0.8
1st speed=0.2   Let x be ratio,then 1st/2nd=x   0.2/2nd =x------&gt;2nd=0.2/x------(a)   .   .   .   7th=0.2/x^6=5.4   x^6=0.2/5.4=1/27-----&gt;1/3^3   x=1 / 3^(3*1/6)-------&gt;1/3^1/2   therefore 2nd speed(from (a)) =0.2/(1/3^1/2)--------&gt;3^1/2*0.2   (3^1/2) (0.2)ns (3^1/2) (0.2)
