Help with my physics...
Question: An airplane travels at 1800km at a speed of 1000km/h. It then encounters a headwind that slows it down to 850km/h for the next 2300km. What was the average speed of the plane for this trip?
The answer according to the sheet is 550km/h, it doesn't explain how this answer was achieved but when I tried it my answer was 909.921671 Km/h. Can anybody get 550km/h? or was I actually right? |
