As per the question, the velocity of the airplane [v] = 660 miles per hour.
The total time taken by airplane [t] = 3.5 hours.
We are asked to determine the total distance travelled by the airplane during that period.
The distance covered [ S] by a body is the product of velocity with the time.
Mathematically distance covered = velocity × total time 
                                                       S = v × t
                                                         = 660 miles/hour ×3.5 hours
                                                         = 2310 miles.
Hence, the total distance travelled by the airplane in 3.5 hour is 2310 miles.
