Sun, a kayaker, paddles 8 miles upstream (against the current) in 2 hours. Returning to her original location, she paddles downs
tream (with the current) the same distance in 1 hour. The equations represent x, the paddling speed, and y, the speed of the current.2(x – y) = a
1 answer:
We calculate both velocities:
upstream 8 miles in 2 hours = 4 miles / hour
downstream 8 miles in 1 hour = 8 miles / hour
ps -stream speed = 4 mph
ps + stream speed = 8 mph
Adding both equations
2 ps = 12 mph
paddling speed = 6 mph
stream speed = 2 mph

X= -5 because you divide -5x by -5 to get x alone so you have to 25/-5 which is -5
(250+300+250+5,268)÷50,000
=0.12136*100=12.1%
Answer:
3 : 50
Step-by-step explanation:
6% = 0.06
0.06 = 6/100
6/100 = 3/50
3/50 = 3 : 50
Your answer will be 1/55 or A because, at the beginning of the problem it states "you are one of 55 people" ((:
49 degree is the answer
tanø = 46/40
= 1.15
Ø = 49 degree
