Stream cleaning days

Conservationists cleaned the stream in three days. On the first day, they cleared one-third of the stream. On the second day, one-third of the remaining portion of the stream, and on the third day, they cleared the remaining 8 km of the stream. How long is the stream?

Final Answer:

x =  18 km

Step-by-step explanation:

r2=(11/3)/3=920.2222   3x+r2 x+8 = x   3x+92 x+8 = x  3 x+2 x+8 9=9 x  4x=72  x=472=18  x=18=18 km
