Question

Mr. Cohen drives 84 2/10 miles on Tuesday, 84 6/10 on Wednesday, and 85 miles on Thursday. What is the rule of the distance he drives each day? Show how you can check your answer.

Answer 1

He drives an extra 4/10 of a mile every day.

Explanation:

Looking at our pattern, we see that to get from 84 2/10 to 84 6/10, we would add 4/10.

Similarly, to get from 84 6/10 to 85, we would add 4/10.

This means we add 4/10 of a mile every day.

To check, we can subtract:

85-84 6/10 = 4/10

84 6/10-84 2/10 = 4/10

Answer 2

He drives an extra 4/10 miles you can check your work by adding 4
