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.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
