27:63
divide both sides by 9
your answer is 3:7
Answer:Final answer: (45,30)
Step-by-step explanation:
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
If you have any questions please ask
SOLUTION:
120 miles = 60 seconds
120 ÷ 240 = 60 ÷ 240
120 × 1 / 240 = 60 × 1 / 240
120 / 240 miles = 60 / 240 seconds
1 / 2 mile = 1 / 4 seconds
1 / 2 mile = 1 / 4 ÷ 60
1 / 2 mile = 1 / 4 × 1 / 60
1 / 2 mile = 1 / 240 minute
FINAL ANSWER:
Therefore, it will take Rachel 1 / 240 of a minute to swim a 1 / 2 mile.
Hope this helps! :)

The area of the pool is equal to its length multiplied by its width. And if you have memorized your times tables you will know that 9 times 8 equals 72. So therefore the amount of water that the swimming pool can hold would be 72 yards squared.
