[Math] How to calculate a distance with different fraction ratios

fractionsratio

This is the math question for my sixth grader son. The answer is $136$ meters but could not figure it out. Can someone please explain how to solve it. Thank you.

Adam first walks $3/8$th of a road. He then walks $2/8$th and $2/3$rd of the road. Since Adam still has $17$ meters to walk. How long is the total journey? (Answer: $136$m)

Best Answer

The question is incorrect as the commentators have shown. If the last $2/3$ should be $2/8$, he has walked $7/8$ of the road and has $1/8$ left, which we are told is $17$ meters. That says the whole road is $8 \times 17=136$ meters, the stated answer.
