Question 530547
Car I rate = xmph
car II rate = 8x/9 mph

They are moving towrads each other so add up their speeds

x+(8x/9)= 17x/9

distance d = 595
rate = 17x/9
time = 7 

d=rt
595= 7*17x/9

multiply equation by 9

595 *9 = 119x
x= 595*9/119

speed of Car I = 45 mph
speed of Car II = 8*45/9= 40 mph
