Question

On your vacation, you take a plane from Atlanta to San Francisco (3400 km). The flight takes 4.0 hours. The first ten minutes and the last ten minutes are spent speeding up and slowing down respectively. Therefore, you reach your top speed 10 minutes into the flight. What was your average speed on this flight?

Answer 1

Answer: S = 850 km/h = 235.11 m/s

Step-by-step explanation:

average speed = total distance : total time elapsed

distance = 3400 km

total time = 4 hours

average speed = D : T = 3400 km : 4 h = 850 km/h

[ 850 km /h = 850 000 m : 3600 s = 236.11 m/s ]
