SOLUTION: Q varies jointly as r and s. If q= 2.4m when r =0.6 and s= 0.8, find q when r= 1.6 and s=.01.

Q varies jointly as r and s.
Q = k*r*s
-------------------
Solve for "k" using "If q= 2.4m when r =0.6 and s= 0.8"
2.4 = k*0.6*0.8
----
2.4 = 0.48k
k = 2.4/0.48
k = 5
-------
Find q when r= 1.6 and s=.01.
Q = 5*1.6*0.01
Q = 0.08
====================
