Answer:
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
