Final answer:
The range of the function that finds the distance in miles of flights lasting 2 to 5 hours based on time is from 840 miles to 2,100 miles.
Step-by-step explanation:
To find the range of the function that finds the distance in miles of flights lasting 2 to 5 hours based on time, we need to determine the minimum and maximum values of the distance.
Let's start with the minimum value. If a flight lasts 2 hours, the minimum distance it can cover is the speed multiplied by time: 420 miles/hour * 2 hours = 840 miles.
Next, let's find the maximum value. If a flight lasts 5 hours, the maximum distance it can cover is the speed multiplied by time: 420 miles/hour * 5 hours = 2,100 miles.
Therefore, the range of the function is from 840 miles to 2,100 miles.
