480=60(v+s)
480=60v+60s
8=v+s
s=8-v...
480=80(v-s) using s from above we get:
480=80(v-(8-v))
6=v-8+v
6=2v-8
2v=14
v=7, and since s=8-v, s=1
So the rate of the team is 7m/s while the rate of the stream is 1m/s
Answer:
Using the Quadratic Formula
x=-b ± √b²-4ac/[2a]
x= -(-5) ± √5² - 4(1)(5)/(2)
x= 5 ± √25-20 /(2)
x= 5 ± √5 /(2)
x= 5 + √5/(2) and 5 - √5/(2)
