Average miles traveled per day = 2.884/7 = 0.142, rounded to nearest hundredths = 0.14

Wait a minute 2.884/7=0.412. How come you got 0.142, then rounded to 0.14?

You can hardly see the comma. She traveled 2,884 miles and the trip took 7 days.
2,884/7=412 miles/day and no need to round off

Georges, it doesn't make sense that a person travels across the country and only travels 2.884 miles in 7 days !
She traveled two thousand, eight hundred eighty-four miles .

You're right, Authur! It's actually 2,884 miles. My mistake.

Athur, could you help me with my other problems? I need to know if i get this one correctly.
Randall recorded 8 songs on his most recent CD. The total length of the CD is 49 minutes. Find a unit rate to represent the average length per song on the CD.
49/8=6.125
rounded= 6.13
Is this correct?
