A boat travels 12 Mph in still water. It can travel 18 miles upstream in the same time that it can travel 24 miles downstream. W
quester [9]

Answer:

The current of the water is 1.714 mph.

Step-by-step explanation:

Let the boat in t hours can travel 18 miles upstream, and  24 miles downstream.

Therefore, if the speed of the boat in still water is 12 mph and that of water is x mph , then we can write  

\frac{18}{t} = 12 - x ........ (1) and  

\frac{24}{t} = 12 + x ............ (2)

Now, adding those two equations (1) and (2) we get,

\frac{18}{t} + \frac{24}{t} = 24

⇒ t = 1.75 hours.

Now, from equation (1) we get

\frac{18}{1.75} = 12 - x

⇒ x = 1.714 mph

Therefore, the current of the water is 1.714 mph. (Answer)

Which value satisfies the inequality x+3/4<8?
Veronika [31]
You want to isolate the x. So you can subtract both sides by 3/4 and get:
x<8-3/4

To do 8-3/4, you multiply the 8 by 4 to get a common denominator of 4.
32/4-3/4 which is 29/4 or 7 1/4

So your final answer is x<7 1/4 or any number less than 7 1/4

Hope this helps!
