Have a great day! :)
R = speed in still water
r + c = speed with current
r - c = speed against current
3.5(r + c) = 70
r + c = 20
c = 20 - r
4(r + c) = distance from pier to pier
5(r - c) = distance from pier to pier
4(r + c) = 5(r - c)
4(r + 20 - r) = 5(r - 20 + r)
80 = 10r - 100
180 = 10r
18 = r
The speed in still water is 18 km/hour
Answer:
Step-by-step explanation:
4(x+6)/(x-2)*(x+10)/24(x+6)
First we do 4(x+6)
4x+24
Then we do 24(x+6)
24x+144
So we plug it in
4x+24/x-2*x+10/24x+144
