An ambulance travels back and forth, at a constant speed,along a road of
length L.At a certain moment in time,an accident occurs at a point uniformly
distributed on the road(i.e. the distance from one of the fixed ends of the
road is uniformly distributed over the length of the road),Assume that the
ambulance's location at the moment of the accident is also uniformly
distributed and is independent of the position of the accident.(a)What is the
distribution of the distance between the ambulance and the accident.(b)What if
the ambulance did not travel at a constant speed but traveled at different
speeds when at different locations?
請各位大大幫忙解答該怎麼做,多謝
