Aboat travels 12 mph in still water. it can travel 18 miles upstream in the same time that it can travel 24 miles downstream. what is the current?
i need it quick.

Current of the water is 1.714 mph

Given that,

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

To find: current of water

Formula to remember:

If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then:

Speed downstream = (u + v) km/hr

Speed upstream = (u - v) km/hr

Let "t" be the time taken for upstream and downstream

Let "x" be the speed of stream or current

For upstream:

distance = 18 miles

time taken = t

speed in still water = 12 mph

speed of stream = "x"

we know that :

For downstream:

distance = 24 miles

time taken = t

speed in still water = 12 mph

speed of stream = "x"

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

Now, from equation (1) we get

Thus current of the water is 1.71 mph

step-by-step explanation:

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2
