An ambulance travels back and forth, at a constant speed, along
a road of length l. at a certain moment of time an accidentoccurs
at a point uniformly distributed on the road. [that is, thsdistance
from one of the fixed ends of the road is uniformlydistributed over
(0, l).] assuming that the ambulance's location atthe moment of the
accident is alsouniformly distributed, compute, assuming
independance, the distribution of its distance from
theaccident.
