Two cars leave an intersection, one 17 minutes after the other. The first car, A, travels north at the speed of 50 km/h and the second car, B, travels west at a speed of 70 km/h. How fast are the cars separating from each other 55 minutes after the first car leaves the intersection? the answer is 85, but I am struggling on how to find that answer
