During a recent track meet, Peter ran x meters of the 100 meter dash in 6 seconds; running at the same rate, how many seconds will it take Peter to run z meters of the 200 meter dash?  Choose the correct choice from the following options.
A) 6z/x
B) 6zx
C) 6x/z
D) 6/xz
E) xz/6
Speed of Peter = x/6 meters per second   Time needed to run z meters = DIST6z/xNCE/SPEED = z / (x/6) = 6z/x   Option 6z/x   The values 100m and 200m have no role to play here and are just given to confuse you.
