Phoenix [80]

Answer: 17/18

Step-by-step explanation: You have to find the least common denominator first, since 1/9 and 5/6 have different denominators. The least common denominator is 18. Multiply both the numerator and the denominator of each fraction by the number that makes its denominator equal to the least common denominator.

The equation then becomes 2/18 + 15/18 which equals 17/18 ^-^

A row team paddles 30 miles upstream in 2 hours and 30 miles downstream in 45 minutes. How fast can the row team paddle in still

sp2606 [1]

Answer:

Rate in still water = 27.5 mph

Current's rate = 12.5 mph

Step-by-step explanation:

Let

x mph = row team rate in still water

y mph = current's rate

<u>Upstream:</u>

Distance = 30 miles

Time = 2 hours

Rate = x - y mph

Then

$30=2(x-y)$

<u>Downstream:</u>

Distance = 30 miles

Time = 45 minutes $=\dfrac{3}{4}$ hour

Rate = x + y mph

Then

$30=\dfrac{3}{4}(x+y)$

From the first equation:

$30=2(x-y)\Rightarrow 15=x-y$

From the second equation:

$30=\dfrac{3}{4}(x+y)\Rightarrow 40=x+y$

Add these two equations:

$15+40=x-y+x+y\\ \\2x=55\\ \\x=27.5\ mph$

Subtract these two equations:

$40-15=x+y-(x-y)\\ \\25=x+y-x+y\\ \\2y=25\\ \\y=12.5\ mph$

Contact [7]

Answer:

The answer is 36 meters long.

Step-by-step explanation:

You start with the difference between 120 and 30 meters. 30 is 1/4 of 120, so all you do is do the opposite with 9. What's 4/1 times more than 9 and you get your answer.
