Final answer:
Seema's total flight time from Lagos to Nairobi is approximately 11 hours and 30 minutes.
Step-by-step explanation:
To find the total flight time, we need to calculate the time taken for each leg of the journey and then add them together. The formula to calculate time is time = distance / speed.
The distance from Seema's starting point to Lagos is 8,300 km and the speed is 1,200 km/h, so the time taken for this leg of the journey is 8,300 / 1,200 = 6.9167 hours. Converting this to minutes, we get 6.9167 * 60 = 415 minutes.
The distance from Lagos to Nairobi is 5,500 km and the speed is 1,200 km/h, so the time taken for this leg of the journey is 5,500 / 1,200 = 4.5833 hours. Converting this to minutes, we get 4.5833 * 60 = 275 minutes.
Thus, the total flight time is 415 minutes + 275 minutes = 690 minutes, which is approximately 11 hours and 30 minutes to the nearest minute.
