# Math question - ratio

#1
I think I have an answer, I was just wondering if anyone could offer some reassurance? TIA!

2 athletes enter a 2,000m race around a 400 metre track. One is faster than their rival. In the ratio of 3:2, how far into the race, will the slower be lapped by the quicker runner?

3 laps? But I'm not sure on method or if my approach is correct for this type of question.

the fast runner completes 3 laps at the same moment the slower one completes 2 laps.

I think the way the question is worded through me off, would you agree that the length of the race is irrelevant?

well if they want the answer as a number of laps then it is irrelevant, if they want the distance covered then you need to know how long each lap is.

By the way the question is worded, I would answer it with the number of laps so I assume I would just answer it with something like: The faster runner (A) passed his rival on A's third lap of the track?

"at the exact point where B has completed 2 laps" would be more precise.
