131/5 divided by 11/1
to divide by fractions, you multiply by the reciprocal and the reciprocal of 11/1 is 1/11...
131/5•1/11 and you just multiply across so the answer is every 131/55 miles. if you want it as a mixed number, it's 2 21/55

We need to divide the length of the course by the number of volunteers. The course is 131/5 miles long, so our expression reads 131/5 ÷ 11. Dividing by 11 is the same as multiplying by 1/11, so we can rewrite the expression as 131/5 · 1/11. This equals 131/55, or 2&22/55 which is our answer.
