Matt will drive about 3,000 miles across the country on interstate 95. he plans to drive 7 hours each day averaging 60 miles per hour. what is the least number of days the trip will take?

7 hours at 60 mph means 7 hours * 60 mph = 420 miles
He will drive 420 miles per day.
To find the number of days, we divide 3000 miles by 420 miles per day.
3000/420 = 7.14
Since the answer is more than 7 days, he needs at least 8 days for his trip.
