Carol jogged 1 3/4 miles on 5 days last week. She jogged 2 1/4 miles on 4days this week. Was her total distance greater last week or this week? How much greater? Explain

This is the concept of arithmetic:

Given that Carol ran a total 1 3/4 miles for 5 days last week, the total distance covered was:

Total distance = (distance per day) * (total number of days)

=1 3/4*5

=7/4*5

=35/4

=8 3/4 miles

Total distance ran this week is:

Total distance = (2 1/4*4)

=9/4x4

=9 miles

therefore we conclude that the distance covered this week was greater than the distance covered last week.

b] this distance was greater by:

difference = (distance covered this week) - (distance covered last week)

=9-35/4

= (36-35) / 4

=1/4

the answer is 1/4 miles
