Here are the solutions to the questions: (iii) If it is 4:40 pm at Bukoba 33° E in Tanzania what will be the time at Accra Ghana 0° Step 1: Find the longitude difference. Bukoba is at $33^\circ \text{ E}$ and Accra is at $0^\circ$. Longitude difference = $33^\circ - 0^\circ = 33^\circ$. Step 2: Calculate the time difference. Every $1^\circ$ of longitude corresponds to 4 minutes of time difference. Time difference = $33^\circ \times 4 \text{ minutes/}^\circ = 132 \text{ minutes}$. Convert minutes to hours and minutes
