A steamer going downstream traveled the distance between two ports in 3 hours. The return trip took 3 hours 40 minutes. Find the speed of the water current if the speed of the steamer in still water is 18 mph.

distance = D

return trip time (RT) = 3 hours 40 minutes.

speed of the water current = VW

steamer speed (SS) =  18 mph

direct trip time (DT) = 3 hours

D = DT x (18 + VW) = 3(18 + VW) = 54 + 3VW

D = RT x (18 -VW) = 3.666 x (18 - VW) = 66 - 3.666VW

54 + 3VW = 66 - 3.666VW

3VW + 3.666VW = 66 - 54

6.666VW = 12

VW = 1. 8 mph

Write an equation of the line with the given slope and y-intercept,(4,3) and (0,1)
PSYCHO15rus [73]

Answer:

y=1/2x+1

Step-by-step explanation:

First use slope formula.

\frac{y2-y1}{x2-x1}

Plug in the information needed.

\frac{1-3}{0-4}=\frac{-2}{-4}=\frac{1}{2}

The slope is \frac{1}{2}.

Now, use point-slope formula.

y-y1=m(x-x1)

Plug in the information needed.

y-3=1/2(x-4)

y-3=1/2x-2

y=1/2x+1

The equation of the line in slope-intercept form is y=1/2x+1.

Hope this helps!

If not, I am sorry.
