A train pulling out of Westmount accelerates from rest at a constant rate. It covers 800 meters in 10 seconds. What is its rate of acceleration?

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )
