Question 930289
 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?
:
I don't think any of these are right
The equation would be: 7x + 7(x-20) = 700
:
Confirm this by solving for x
7x + 7x - 140 = 700
14x = 840
x = 60 meters per minute is Steve's rate
then 40 meters/min is Dave's rate
Find the distance each traveled
7*60 = 420 m
7*40 = 280 m
------------
total 700m
