I posted a question as thus : A train moving at 100 km/hr uniformly decelerates at a rate of 10 km/hr each hr. How far does it travel before stopping ? A few people interpreted the wording of the question to mean the train travels through each hr at a constant speed and then on the cusp of the hr instanteously decelerates by 10 km /hr . Their rational is that the stated deceleration of 10 km/hr 'each' hr somehow contadicts the statement uniformly decelerates. They argue the question is ambiguous . Do they have a point . Or are they misreading the question.
