two cars start from two towns 400 miles apart and travel towards each other.
they pass each other after 4 hours.
find the speed of each if the difference between their speeds is 20 miles per hour
:
Let s = speed of the slower car
then
(s+20) = speed of the faster car
:
When they meet, they will have traveled a total of 400 mi
:
Write distance equation
:
slow car d + fast car d = 400 mi
4s + 4(s+20) = 400
solve for s
