We know that
1 mile----------------> 1609.34 meters
26 miles---------------> X
X=26*1609.34=41842.84 m
I apply a rule of three to know the time
if 100 m---------------9.96 sec
41842.84 m----------> x
x=41842.84*9.96/100=4167.5468 sec
to get minutes I divide it by 60---------> 4167.5468/60=69.459113 minutes
to get hours I divide it by 60----------> 69.459113/60=1.1576518 hours
1.1576518= 1 hour 9 minutes 27.55 sec
the answer is 1 hour 9 minutes 27.55 sec------->(4167.5468 sec)
