You can put this solution on YOUR website! Bad question!!
1-Are they going in the same direction from the same place?
2-Are they going in opposite directions from the same place?
3-Are they heading towards each other from an unknown distance apart?
#1 and #3 will meet.
#2 might never meet.
Should I guess which one you mean?
Assuming #1
A car leaves at 10:00 going 60 miles per hour another car at 12:00 going 75 Miles Per Hour. When will they meet
60(x+2)=75x
add x to 10:00
