A flight from houston to chicago is approximately 940 miles. A plane making this flight is traveling at an average rate of 485 miles per hour. Which function represents the plane's distance d in miles from chicago t hours after leaving houston?

D(t) = 485t + 940

Step-by-step explanation:

D(t) = ?

We are told that the flight itself is 940 miles. This is a constant value, it will not change.

D(t) = ? + 940

Following this, we are also told the plane travels at 485 miles per hour. MPH usually indicates multiplication. 485 miles per each of hour (time here is represented by the variable t). 485t

D(t) = 485t + 940
