You can think of this as 1 snail being fixed and the
other moving at the sum of their speeds.
Let the speed of the moving snail =
+x+%2B+x+-+2+ cm/min
given:
+432+=+%28+2x+-+2+%29%2A27+
+432+=+54x+-+54+
+54x+=+432+%2B+54+
+54x+=+486+
+x+=+9+
and
+x+-+2+=+7+
The snail's speeds are
9 cm/min
7 cm/min
------------
check answer:
Faster snail:
+d%5B1%5D+=+9%2A27+
+d%5B1%5D+=++243+
Slower snail:
+d%5B2%5D+=+7%2A27+
+d%5B2%5D+=+189+
and
+d%5B1%5D+%2B+d%5B2%5D+=+243+%2B+189+
+d%5B1%5D+%2Bd%5B2%5D+=+432+ as it should be
