Carly takes three steps to walk the same distance as Jim walks in four steps. Each of Carly's steps covers 0.5 metres. How many metres does Jim travel in 24 steps?
(A) 16
(B) 9
(C) 36
(D) 12
(E) 18

Part B: Each correct answer is worth 6.
Since the distance covered by Jim in 4 steps is the same as the distance covered by Carly in 3 steps, then the distance covered by Jim in 24 steps is the same as the distance covered by Carly in 18 steps.

Since each of Carly's steps covers $0.5 \mathrm{~m}$, then she covers $9 \mathrm{~m}$ in 18 steps, ie. Jim covers 9 $\mathrm{m}$ in 24 steps.

ANSWER: (B)
