Concept:Distance along the same line of longitude can be converted to latitude difference using $1^\circ$ of latitude $\approx 111$ km.Explanation:Since P and Q lie on the International Date Line, they share the same longitude.So the distance between them is measured along a meridian, i.e. north-south.$1^\circ$ of latitude $\approx 111$ km.Latitude difference $= \frac{444}{111} = 4^\circ$.Town P is at $3^\circ$N and both towns are in the same hemisphere.Therefore, town Q must be further north of P.Latitude of Q $= 3^\circ\mathrm{N} + 4^\circ = 7^\circ\mathrm{N}$.Answer:B. $7^\circ$N
