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
\(2(x+(x+5))=210\)
\(2x+5=105\)
\(2x=100\)
\(x=50\)
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
