Question 456049
A small airplane flies at 145 miles per hour in still air. 
It took 2.5 hours for the airplane to fly D miles against a headwind blowing toward the airplane at W miles per hour. 
----
distance = rate*time
D = (145-w)2.5

Which of the following equations can be used to represent this informmation? 
A) D= (W-2.5)145
B) D=(145-w)2.5
C) 145=(w-2.5)D
D) 145=(D-w)2.5
