Vector Addition of differing quantities

[ilackinsight]

My girlfriend had this problem on her first tutorial sheet at Univeristy. She is doing maths. I am doing physics and was interested in the answer.
It asked what the result was when a displacement vector was added to a velocity vector. The vector addition can obviously be done on these two quantities, but does the end answer actually mean anything? I would think it would be meaningless

Thanks.
Tom.

No need to go to vectors to talk non-sense! What 3 feet plus seven dollars? What is 4 mi/hr+ 3 seconds? What is 2 degrees celsius+ 5 gallons?
See we can all play!

The only good answer to the question posed is "a meaningless quantity"!
