Sagot :
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
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
