Show Worked Solution

\(15^{\circ}\ =\text{1 hour time difference}\)

\(\text{Longitudinal distance}=45^{\circ}\)

\(\text{Time Difference}=\dfrac{45}{15}=3\ \text{hours}\)

  
\(\text{Time in Sydney}\ =\ 3:00\ \text{pm}\)

\(\text{Since Sydney is East of Tokyo:}\)

\(\text{Time in Tokyo}=\ 3:00\ \text{pm}-3\ \text{hours}=\ 12:00\ \text{pm}\)

\(\Rightarrow D\)
