On a map of Nunavut, a length of 1 centimetre measured on the map represents a real distance of 60 kilometres. What length on the map represents a real distance of 540 kilometres?
(A) $9 \mathrm{~cm}$
(B) $90 \mathrm{~cm}$
(C) $0.09 \mathrm{~cm}$
(D) $0.11 \mathrm{~cm}$
(E) $5.4 \mathrm{~cm}$
Since a real distance of $60 \mathrm{~km}$ is represented by $1 \mathrm{~cm}$ on the map, then a real distance of $540 \mathrm{~km}$ is represented by $\frac{540}{60} \mathrm{~cm}$ or $9 \mathrm{~cm}$ on the map.

ANSWER: (A)
