Final answer:
To find the average speed of an airplane for its total trip, calculate the total distance, determine the time taken for each segment, sum up the total time, and divide the total distance by the total time.
Step-by-step explanation:
The average speed of an airplane for a total trip is calculated by dividing the total distance traveled by the total time taken. In this scenario, the airplane flies 244 miles at 732 mph and 918 miles at 612 mph.
To find the average speed (Vavg), we first calculate the time for each segment of the trip:
- Time 1 = Distance 1 / Speed 1 = 244 miles / 732 mph
- Time 2 = Distance 2 / Speed 2 = 918 miles / 612 mph
Then we add the times to find the total time:
Total Time = Time 1 + Time 2
Next, we find the total distance:
Total Distance = Distance 1 + Distance 2
Finally, we calculate the average speed:
Vavg = Total Distance / Total Time
The total distance is 244 miles + 918 miles, and the total time is calculated from the given speeds.
