The answer is 96 min, here is why:
x / 240 + x / 160 = 1
<span>2x + 3x = 480 </span>
<span>5x = 480 </span>
<span>x = 96 min
(</span><span>Drainage rate of first pipe = 480000/240 = 2000 l/min </span>
<span>Drainage rate of second tube = 480000/160 = 3000 l/min </span>
<span>Combined drainage rate = 5000 l/min </span>
<span>Time to drain = 480000/5000 = 96 min. )</span>

Answer:
n=-3
Step-by-step explanation:
11(n – 1) + 35 = 3n
expand left side
11n-11+35=3n
Add-11 to 35
11n+35-11=3n
11n+24=3n
subtract 24 from both sides
11n+24-24=3n-24
11n=3n-24
subtract3n from both sides
11n-3n=3n-24-3n
8n=-24
divide both sides by 8
8n/8=-24/8
n=-3
