You can put this solution on YOUR website! Cheyenne will drive 3,000 miles across Interstate 90. She plans to drive 7 hours each day averaging 60 miles per hour. What is the least number of days the trip will take?
.
Applying the distance formula:
d = rt
where
d is distance traveled
r is rate or speed
t is time
.
Each day Cheyenne travels:
7*60 = 420 miles
.
Number of days, then, to travel 3000 miles:
3000/420 = 7.143
Since she takes MORE than 7 days, the "least" number of days then is
8 days (answer)
