Answer:

X = 560

Step-by-step explanation:

Speed = distance / time

Distance = 2660 miles

Time taken = 4.75 hours

Writing the equation in terms of proportion :

Rate or speed = Distance : time

Speed = 2660 : 4.75

Reducing to lowest term ;

Divide both sides by 4.75

Hence, we have ;

Speed = 2660/4.75 : 4.75/4.75

Speed = 560 : 1

Comparing with the proportion in the question, X = 560
