Question 411103
 Noah runs at 7 mph, Ben runs at 5 mph. If they start at the same time,
 how long (in minutes) will it be before they are 1/6 mile apart?
:
Convert the speed to ft/min
{{{(7*5280)/60}}} = 616 ft/min
{{{(5*5280)/60}}} = 440 ft/min
convert 1/6 mi to ft
{{{1/6}}}*5280 = 880 ft
:
Let t = time in minutes for this to be true
:
N's dist - B's dist = 880 ft
616t - 440t = 880
176t = 880
t = {{{880/176}}}
t = 5 minutes
