Homework Help: Science (8th grade)

Posted by Ji on Saturday, February 9, 2013 at 4:36pm.

I am doing a lab and I really need help!

I calculated that my snail traveled as his average speed of .136 cm/s, 1.36m/s, and 4896 m/hr.

Does that sound right?

Also I need help on another thing. My paper says Calculate how long it will take your snail to cross a sidewalk (2m) cross a road (20 m).

How would I figure that out?

Last thing.
It says, use your graph to compare average speed and the speed of an object along a path. Are they always that same? Give evidence by marking on a graph where speed over a 30 second interval is faster or slower than average speed.

What does that even mean???? I'm so confused!

Please help!

This is due soon!!!!

Thanks so much!
