<PRE><B>Question 524683</B>
They determined that one was crawling at a pace of 15 mm/min and the other at 10 mm/min. At these rates, how long will it take for the snails to be 10 CENTIMETERS apart?
----
rate*time = distance
-----
1st snail: 15mm/min*t min = 15t mm
---
2nd snail: 10mm/min*t min = 10t mm
=======================================
Distance + Distance =  10 cm = 100 mm
----
15t + 10t = 100 mm
25t = 100
t = 4 minutes
===================
Cheers,
Stan H.
