Answer:
r60 gallon a day if it is wrong i'm sorry
Step-by-step explanation:
D=vt
So they will travel downstream and upstream the same distance. Downstream they will travel:
d=(2+18)t1
Upstream they will travel:
u=(18-2)t2
Since d=u we can say:
20t1=16t2
We are told the trip lasts 3 hours so t1+t2=3, t2=3-t1, using this in the equation above we have:
20t1=16(3-t1)
20t1=48-16t1
36t1=48
t1=4/3 hours, and from earlier we saw that d=20t1 so:
d=20*4/3
d=80/3 miles
d=26 2/3 miles.

Answer
y=2/5x-2
Step-by-step explanation:
The slope-intercept equation for a straight line is y=mx+b,
where m is the slope and b is the y-intercept.
Here, m=2/5 and b=-2
⇒ y=−2/5x-2
