Calculate the local time of Nigeria longitude 45 degree east, if the time of Ethiopia is 5:00pm, longitude 30 degree east.

Please answer my question step by step.

Step 1: Calculate the time difference between Nigeria and Ethiopia.

Nigeria is located 15 degrees east of Ethiopia (45 - 30 = 15). Each degree of longitude is equal to 4 minutes of time difference. Therefore, the time difference between Nigeria and Ethiopia is 60 minutes (15 x 4 = 60).

Step 2: Calculate the local time of Nigeria.

Since Nigeria is located 15 degrees east of Ethiopia, the local time of Nigeria is 5:60pm (5:00pm + 60 minutes = 5:60pm).
