Ratio of the distance to tree from car and from person, is 24:6 or 4:1. So the person should maintain a speed of 35mph/4 ~= 9 mph
Okay, suppose the car is travelling with velocity , the tree has diameter and is at distance from the road; suppose the hidden person is hugging the tree, and that, looking down from above, the person, car and centre of the cross section of the tree trunk are always in a straight line.
Then I make it the speed of the person when the distance between the tree and the car is is .
You also need to know the diamter of the tree trunk.
Is this a problem that can be solved?
