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.
