<PRE><B>Question 944249</B>
25 laps in 6 hrs Number laps/time=rate  25 laps/6 hrs=4.1667 laps/hr
Or for time per lap  1 lap=1 hr/4.1667 laps=0.24 hrs/lap
Convert to minutes/lap:(0.24 hrs/lap)(60 min/hr)= 14.4 min/lap
Number of laps times time/lap=total time (60 laps)(0.24 hrs/lap)=14.4 hr
OR
For the above problem, let T=total time 
{{{25 laps/6 hrs=60 laps/T}}} Multiply each side by T
{{{(25 laps*T)/6 hrs=60 laps}}} Multiply each side by 6 hrs
{{{25 laps*T=360 lap-hrs}}} Divide each side by 25 laps
{{{T=360/25 hrs}}}=(14.4 hr)
