Question

A student solved this problem and said the answer was 5 miles.

Danielle ran 3 miles on Tuesday, 4 miles on Wednesday, and 5 miles on Thursday. How far did Danielle run altogether?



Is the student's answer reasonable?



A.
Yes, the answer is reasonable.


B.
No, the answer is not reasonable. It should be about 2 miles.


C.
No, the answer is not reasonable. It should be about 13 miles.


D.
No, the answer is not reasonable. It should be about 20 miles.

Answer 1

I think the answer is C. No, the answer is not reasonable. It should be about 13 miles because of the fact that 3 miles+ 4 miles +5 miles =12 miles, which is close to 13. Hope this helps!

Answer 2

Greetings!

Option C would be correct.

3 + 4 + 5 = 13 therefore, C is the best answer.

Hope this helps!
