On the 5 hour flight from Dallas to New York, the airplane was flown at an altitude of 1200 feet. For 35% of this time, the flight flies over water. How many hours is the flight over water?

Respuesta :

5 x .35 = 1.75 h 
therefore the plane is flying over water for 1h 45 min
1.75 / 1 Hour and 45 Minutes.
