Answer:
5.2 hours or 312 minutes
Explanation:
The plane route has been given as 260 miles.
We're told that the car/road rouge is 10% longer, and that is 260 * 1.1, which is equal to 286 miles.
Now, the car travels at 55 miles per hour, and we're to calculate how long it will take to travel.
Speed = distance / time
Making time the subject of formula, we know that
Time = distance / speed
Time = 286 miles / 55 miles per hour
Time = 5.2 hours, converting to minute, we have 5.2 * 60 = 312 minutes.
