Answer:
262.12mph and 419kph
Step-by-step explanation:
Given: It takes 4 hours and 15 minutes to fly from Orlando, Florida, to Boston, Massachusetts. The distance between the two cities is 1114 miles
To Find: the average speend of the plane in miles per hour, If every mile is approximately 1.6 kilometers, the speed of the airplane in kilometers per hour
Solution: 
Distance between Orlando,Florida and Boston, Massachusetts 
 
Time taken to cover the distance  and
 and 
We know that,

                                           
                                           
                                            
 
It is given that,

therefore,

Speed Of plane in Kilometers per hours 
                                                                    
Speed of in miles per hour  is  
  and Speed in kilometer per hour
 and Speed in kilometer per hour
