which car has to cover distance x?
time = distance/speed
no diagram to refer to here.
Two cars lost in a blinding snowstorm are traveling across a large field, each thinking they are on the road, as shown in the figure on the left. They collide. If the distance x is 141 meters and the red car is travelling at 19.5 mph, how fast to the nearest hundredth of a mph was the blue car travelling? (As unlikely as this event seems it actually happened to the problem author's wife.)
