An airplane flies 3800 km in 4 hours 45 minutes. What is its average speed in kilometers per hour?
8_murik_8 [283]

Average speed = (distance covered in some time)  /  (time to cover the distance)

4 hours 45 minutes = 4-3/4 hours = 4.75 hours

Average speed  =  (3,800 km) / (4.75 hours)  =  800 km/hr
