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!

No. Please check to be sure that the snail travels at 0.136 centimeters per second.
0.136 cm/s = 0.000136 m/s
1 hour = 60 * 60 = 3600 seconds
3,600 * 0.000136 = 0.4896 m / hour 
for part 1, consider that your average jet plane flies at about 600 mph
No way your snail goes 4896 mph.
I'd think that a snail probably travels about 0.136 cm/s
That's what I'd call a snail's pace.
Since that's hard to measure, try seeing how far it travels in 10 seconds. 
You just forgot to include the decimals :) a snail dosen't go over 4000 mph! Use common sense before turning these things in. Once said a turtle went 50 mph on a test,,, silly me
