A boat has a speed of 15 mph in still water. It travels downstream from Greentown to Glenavon in g hours. It then goes back upst
valentina_108 [34]

Answer:

The distance from Greentown to Glenavon is D1 = g*(15+x) miles downstream.

The distance from Glenavon to Cambria is D2 = g*(15-x) miles upstream.

The difference D1 - D2 is 2 miles, according to the condition.

It gives you an equation g*(15+x) - g*(15-x) = 2, which you can easily solve and find "x", the rate of the current. x = 1/g miles per hour.

I am needing to know the answer to 3/7 of what number is 9?
kolezko [41]
In math, "of" almost always means "times".

So your question is:  3/7 times (the number) = 9

Multiply each side of that equation by  7 :   3 times (the number) = 63

Divide each side by 3 :             <em> The number = 21</em>
