There was another one like this earlier, and the time information was lacking. This one here is better.
Let r = speed of the slower car.

Car ------Speed, km/h-------Time, hours----------Distance, km
Fast car___r+7______________2____________________
Slow car____r ______________2 ___________________

The cars start 300 km apart and move toward each other, so sum of all lengths or distances must be 300.

Find r.
Compute r+7.
