Answer:
m (parallel) =
3
/4
Step-by-step explanation:
on the graph Y will start on two
R=rate of boat in still water
c=rate of current
d=rt
since you're given that the time it takes to travel the same distance downstream and upstream, your equation will be d_1=d_2, or rt=rt
the rate upstream is r-c and the rate downstream is r+c (because the boat's and river's rates add up)
since you know t_1 and t_1 are 5 and 3, you can now set up 2 equations
<u>5*(r-c)=45</u> because (time upstream)*(rate upstream)=distance=45 miles
r-c=45/5=9
<u>3*(r+c)=45</u>
r+c=45/3=15
r-c=9 and r+c=15, so r=12 mi/h and c=3 mi/h

Answer:
i would pick 700.
Step-by-step explanation:
but im not sure this seems hard.
Step-by-step explanation:
there is 3 feet in a yard
divide by 3
18 ÷ 3 = 6
true
3^2 + 16
= (3 • 3) + 16
= 9 + 16
= 25
