I checked with teacher, its wrong.
Only 1 out of 96 students got it correct!
So hard, good try, though
Answered by Ms. Sue
Yes, 11.7 miles on Sunday
Answered by Ms. Sue






















I got the same answer.

What does your teacher say is the right answer.








Answered by Anonomous
It was a test, computer checked it, computer said it was wrong
Answered by Anonomous
The teacher does not explain it.
She wants us to do it by ourselves
Answered by Ms. Sue
Baloney! The computer was wrong. Your "teacher" is not a real teacher if s/he does not explain it.

I've seen many wrong computer answers on Jiskha.

Also if only 1 out of 96 gets a problem correct, there is something wrong with the problem.
Answered by Reiny
I agree 100% with Ms Sue

the correct answer to the question as stated is 11.7

doesn't matter what the computer or your teacher says
Answered by Ms. Sue
This is a fake school if the teacher won't explain.

Answered by Henry
d = 1.5(3.6+4.2) = 11.7 miles.

Do your teacher know how to solve the problem?

Can she get the opinion of another math teacher at the school?
