Question 156863: At 11:00a.m. Kate left the Clinton toll booth traveling west at 80 km/h. At 12:00p.m. Juan left the toll booth traveling west at 72 km/h. At what time will the two cars be 98 km apart?
This is what I have so far...Kate: 80(x+1)
Juan: 72x
80(x+1)+72x=98
152x=18
x=.118
Not sure what to do after this..thanks.

Question 158814: The sum of the squares of three consecutive even integers is 116. Find the integers...
This is what I have tried...
x + (x + 2)+ (x + 4)= 116
3x + 6 = 116
-6 - 6
3x = 110
3x/3 110/3
x = 36.6666
