Final answer:
The time it takes for an airplane to fly from Buenos Aires to Cape Town at an average speed of 800 km/h, for a distance of 6900 km, is approximately 8 hours and 38 minutes.
Step-by-step explanation:
To calculate the time it takes for an airplane to fly from Buenos Aires to Cape Town at an average speed of 800 km/h, covering a distance of 6900 km, we can use the formula for time, which is:
Time (t) = Distance (d) / Speed (s)
Plugging in the given values:
t = 6900 km / 800 km/h
After dividing the distance by the speed:
t = 8.625 hours
To provide a more practical figure for travel, we typically round the flight time to the nearest minute. So, we multiply the fractional hour by 60:
0.625 hours * 60 minutes/hour = 37.5 minutes
Therefore, the total flight time is approximately 8 hours and 38 minutes.
