Question 1201375
<br>
If it takes her 6 minutes to run each lap, then the total time to run x laps is 6x minutes.  We are told that the number of minutes she ran is less than 42:<br>
{{{6x < 42}}}
{{{x < 7}}}<br>
Nothing in the statement of the problem says the number of laps has to be an integer....<br>
ANSWER: less than 7<br>
Of course, a negative number of laps makes no sense, so the answer {{{x<7}}} is not COMPLETELY correct mathematically.  The better answer is probably {{{0<=x<7}}}.<br>
