<PRE><B>Question 523880</B>
If a group of people walk about 3mph and they are led by a car traveling 5mph -How far apart will they be at 1/4mile?
:
Let t = time for them to be 1/4 mi behind the car
:
Write a distance equation, dist = speed * time
:
car dist - walker dist = 1/4 mi
5t - 3t = {{{1/4}}}
2t = {{{1/4}}}
multiply both sides by 4
4(2t) = 1
8t = 1
t = {{{1/8}}} hr Or: {{{1/8}}}*60 = 7.5 minutes
