Answer: Ground speed of the airplane is 460 mph.
Step-by-step explanation:
Step 1: Speed of the headwind with which the airplane is travelling = 480 mph.
Air speed is = 20 mph
Step 2: We are asked to use the formula g= a-h, where g is the ground speed, a is the sir speed, and h is the speed of the headwind.
Using the formula, g= (480 - 20)mph = 460 mph
Final ans: Ground speed of the airplane is 460 mph.
