Please can someone help explain how I do this problem: Two students are running laps around a track. Student A completes one lap in 1.5 minutes. Student B completes one lap in 1.75 minutes. If they start at the same time, how long will it be until they finish a lap at the same time?

when student B starts their 7th lap

Step-by-step explanation:

if they keep running at the same speed and completing at their same times, every time a lap is completed, their timer doesn't reset but their distance from the finish line does. if my answer is incorrect, that means i used my own equation because you did not provide the equation that you have to use.

your question is incomplete, write all the numbers in the sequence that it tells you.
