usually you would place a couple of stakes across the glacier and over time you would see them move. so it would be the distance that the moved over the time it took. usually the stakes towards the middle will move the fastest because they are less affected by friction. you could also just clock it with a speed gun....
When a glacier's rate of melting exceeds its rate of movement, excess meltwater can accumulate at the surface, leading to the formation of melt ponds and potential for surface water to drain through crevasses, lubricating the base and potentially increasing sliding speed. This imbalance can disrupt the glacier's stability and potentially accelerate its flow towards the terminus.
An iceberg is a body of ice floating in the ocean. A glacier is a land based 'river of ice' flowing from the mountains to its ultimate terminus, wherever that may be. Thus they are very different things. As to speed, like a river, that depends upon the gradient - in the cirques at the head, the velocity would be quite high, but slowing as the glacier grew and its gradient shallowed.
A galloping glacier is a glacier that, unlike others of their type which move at inches per day, shoots ahead feet per day, an astonishing rate for glaciers. The nickname "the galloping glacier" has also been given to an Alaskan black rapids glacier which set a record for its speed. Galloping glaciers are most likely caused by extra melted snow lubricating the glacier.
That area is known as the ablation zone, where the rate of melting exceeds the rate of snow accumulation. It is located at the lower end of the glacier and is crucial in determining the overall health and size of the glacier.
a glacier has a snowline at the same height as the wastage line.

A growing glacier is one where the rate of deposition of snow at the source exceeds the rate of loss of ice at the tow. In other words, a glacier which is getting bigger/longer.

Boulder Glacier is shrinking at an increasing rate, such that it will not be classified as a glacier soon (if not already). See the link below for repeat photos.
