ok this math question says "If a Snail travels 2000 inches in 2 hours how long does it take to travel 50 inches?" Can someone tell me how to do this and what i should get please?
i was thinking i need to take 2000 and divide it by 2 and than - 50 and i get 950. is that right?
thanx for any help

2000inches----120min
50inches-------50*120/2000
=3min

The snail travels 2000 inches in 2 hours
Hence for travelling 1 inch,it would take 2/2000 hr
And for travelling 5o inches it would take 2x50/2000 or 1/20 hrs
Now you may convert the time of 1/20 hour in minutes by multiplying it by 60 to get 60/20 or 3 minutes.

Set up a proportion. I think it is the easiest way. Like this 2000/120 (use 120 minutes instead of hours) = 50/x Now cross multiply. Multiply 2000 times x, and 120 times 50. you should get 6000 = 2000x. Now divide to find x. You should get 3 minutes.

(2 hours / 2000 inches) * (50 inches) = 5/100 hours = 300/100 minutes = 3 minutes

s = snail's speed
t = time
s = distance/time = 2000 in / 2 hours = 1000 in/hour
t = distance/s = 50 in/(1000 in/hr) = (1/20) hr = 3 minutes

2000 inches in 2 hours.
So....2000 inches in 120 minutes.
2000 inches = 50 inches
___________ _________
120 minutes X
50 * 120 = 2000 * X
50 * 120 = X
________
2000
X = 3 min
