Concept:Local time changes by one hour for every $15^\circ$ of longitude.A difference of $45^\circ$ in longitude causes a time difference of $45^\circ \div 15^\circ = 3$ hours.Explanation:The prime meridian, longitude $0^\circ$, passes through Accra.The given local time is $12$ noon at longitude $45^\circ W$.This location is to the west of Accra.Time increases toward the east.Therefore, Accra is ahead of longitude $45^\circ W$ by $3$ hours.Add this time difference to the given local time: $12$ noon $+ 3$ hours $= 3$ pm.Answer:D. $3$ pm
