<PRE><B>Question 278701</B>
Two men in towns 400 miles apart drive to a house on the line between their towns.  They meet after 4 hours.  What is the speed of each car if one of the cars is going 20 mph faster than the other car?

x = other car

20mph + x = one car


Distance = Rate x Time

400 miles = (20mph + x)(4 hours)

400 = 80 + 4x

320 = 4x

80 mph = x (other car)

20 + x = 100 mph (one car)
