1 answer:
Alexxx [7]3 years ago
3 0

Answer:

48+23(6)½

Step-by-step explanation:

A = l × w

A =[(8-(6)^½) × (9+4(6)^½)]

A =8(9+4(6)^½) + [-(6)^½(9+4(6)^½]

A =(72 + 32(6)^½ - 9(6)^½ - 24)

A =(72 - 24 + 32(6)^½ - 9(6)^½)

A =(48 + 23(6)^½)

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)
