<PRE><B>Question 560216</B>
 janet can shovel snow in 55 mins. Tom can shovel snow in 40 mins. How long would it take them to shovel snow if they worked together?
-----
Janet rate = 1/55 job/min
------
Tom rate = 1/40 job/min
------
Together rate = 1/x job/min
==================================
Equation:
rate + rate = together rate
1/55 + 1/40 = 1/x
---
40x + 55x = 40*55
-----
95x = 40*55
----
x = (11/19)40
---
x = 23.1579 minutes
--
x = 23 min 9.47 seconds
===========================
Cheers,
Stan H.
