Question 1157868

Pam and Matt, working together, can weed the garden in 8 hours. Working alone, Matt takes twice as long as Pam. How long does it take Pam to weed the garden alone?
<pre>Let time Pam takes be P
Then time Matt takes is 2P
We then get: {{{matrix(1,3, 1/P + 1/(2P), "=", 1/8)}}}
8 + 4 = P ------ Multiplying by LCD, 8P
Time Pam takes, or {{{highlight_green(matrix(1,4, P, "=", 12, hours))}}}
