Montreal and Quebec City are about 260km apart along Route 20 in Canada.
Sylvia is leaving Montreal to go to Quebec City at a speed of 90km per hour. And Anne is leaving Quebec City to go to Montreal at a speed of 105km per hour.

a) When and where do Slyvie and Anne pass each other? (Assume that neither one stops along the way. Include a table or a graph with your answer.) Hint: When are they the same distance from Montreal?

b) Write an equation to model this situation. Then show how to solve the equation.

HELP!

Ok so just make a table.

Sylvie 90 180 270 360 450 540
--------------------------------
Anne 105 210 315 420 525 630

and so on. Just keep continueing the numbers until you come across the same numbers at the same time.

For the equation it should be 260-90s=260-105.

I'm not sure so you might wan to check with someone else.
