Two cars leave Calgary at the same time, travelling in opposite directions. Their average speeds differ by 5 km/h. After 2 h, they are 210 km apart. Find the speed of each car.

Let the first car's average speed be x

The second car's speed would be x+5

[tex]2(x+(x+5))=210[/tex]

[tex]2x+5=105[/tex]

[tex]2x=100[/tex]

[tex]x=50[/tex]

So the speed of the slower car is 50mph, and the speed of the faster car is 55mph

i think the answer is 50 and 55 but to check that u can multiply both of them by two and then add them together and see if it = 210
