Answer:
Explanation:
The distance traveled by the plane can be represented by the expression: distance = speed x time
In this case, the speed of the plane is given as x-110 mph and the time it travels is 3.5 hours.
So the expression for the distance traveled is:
distance = (x-110) * 3.5 miles
This expression represents the distance traveled in miles. The variable x represents the speed of the plane in mph.
