880-915 km/h
360 km/h
200 km per hr
An airplane travels 80 km in 10 minutes and then flies 100km in 20 minutes the average speed of the plane is? 80 km in 10 minutes = 8 km/min 100km in 20 minutes = 5 km/min Average speed = total distance traveled ÷ total time Average speed = 180 km ÷ 30 min = 6 km/minute Notice the average speed is closer to 5 km/min, because the plane spends twice as much time traveling at the slower speed.
800 Km/hr
a small airplane flies in a straight line at a average speed of 150 km/hour .how long dose it take the plane to fly 250 km
Around 95 mph.
average speed = total_distance/total_time = (80 km + 100 km)/(10 min + 20 min) = 180 km/30 min = 6 km/min 1 hr = 60 min → 6 km/min = 6 × 60 km/h = 360 km/h
if something takes X hours to travel Y km it's average speed is Y/X km/hourIn this case it's 820 km/hour
A woman throws a baseball from the front of an airplane to the back. From the perspective of the woman, the baseball travels at an average speed of 15 m/s. To an observer on the ground, the airplane is traveling at a constant speed of 820 km/h. What is the speed of the baseball from the perspective of the ground observer?
Distance = Speed*Time = 407 kph*7 hr = 2849 km
Speed is NOT measured in km but km PER HOUR. The average speed was 88.88 (repeating) km per hour.
It would take 5530/790=7 hours to reach its destination.
