<PRE><B>Question 930289</B>
Dave and steve are 700 meters apart from each other on a straight path. Both start walking toward each other and meet each other after 7 minutes 
Dave covers a distance of x meters in one minute, which is 20 meters less than the distance steve covers in a minute. Which of these equations can be used to find the rate at which steve and dave walk?
Dave DATA:
rate = x meters/min ; time = 7 min ; distance = r*t = 7x meters
------------
Steve DATA:
rate = x+20 meters/min ; time = 7 min ; distance = r*t = 7(x+20) meters
----
Equation:
distance + distance = 700 meters
7x + 7(x+20) = 700
