Well if you are driving 40 miles PER hour, it means it takes 1hour to drive 40 miles.
So we know how long it would take to drive 40 miles at 40mph, but there is an extra 20.
To do this we just use simple halfing.
At 40mph, it would take 1HOUR to drive at 40mph, so if we think, oh it would take 30minutes to go 20 miles at 40miles per hour.
So your answer is 1 hour 30 minutes.

If you were driving 65 miles per hour how long will it take you to drive 310 miles?
That depends on the speed at which you are driving. For example, if you are driving 52.6 miles/hour, it would take an hour to drive that far. If you are driving 23.8 miles/hour, it would take two hours to drive that far.
