In the 14 minutes, the truck at 60mph (1 mile per minute) travels 14 miles.
When the car enters the highway, it is 14 miles behind the truck; and it is traveling 6mph faster than the truck.
The time required to make up 14 miles distance (i.e., to travel 14 miles farther than the truck and thus catch up to the truck) traveling 6mph faster is 14/6 hours, which is 14*10 = 140 minutes.
