Question 1133998
 Noah runs at 7 mph, Ben at 5 mph.
 If they start at the same time, how long (in minutes) will it be before they are 1/5 mile apart? 
:
Let t = time for this to be true
Write dist equation; dist = speed * time
N's dist - B's dist = 1/5 mi
7t - 5t = {{{1/5}}}
2t = {{{1/5}}}
t = {{{1/5}}} * {{{1/2}}}
t = {{{1/10}}} of an hr
change to min
{{{1/10}}} * 60 = 6 min
