About 48 minutes. This assumes you travel at a constant speed with no stops.

Traveling 50 miles in 1 hour, it takes 0.8 (40/50) hours or 48 minutes to travel 40 miles.
At 80mph, it takes 45secs to travel one mile (three-quarters of a minute). Therefore it will take three-quarters of 48mins to travel the specified 48 miles. 48x 0.75 = 36mins, unless there is a policeman with a speed gun in the way!
