Step-by-step explanation:

The journey began at 10:00. The distance moved from this time is 110 miles. The cruise control is always set at 55 miles per hour. This means 110 miles was covered driving at a speed of of 55 miles per hour.

Speed = distance / time

Time = distance/speed

Time at which 110 miles was covered will be 110/55 = 2 hours

So at 12:00 o'clock, I have covered 110 miles.

I then get hungry and take an hour break to eat lunch. After eating lunch for one hour, I resumed the journey at 13:00.

I drove 165 miles after the break.

The time taken to drive 165 miles

= distance / speed

= 165/55 = 3 hours

Total hours spent is 2 hours before the break + 1 hour break + 3 hours after the break = 6 hours

The trip ended at 16:00
