Can someone show me how to solve this? A boat took 5 hours to travel 60km up a river, against the current. The return trip took 3 hours. Find the speed of the boat in still water and the speed of the current.

Answers

Yes, I can.

And even though you haven't asked to be shown how to do it,
I'll go ahead and do that too:

Call the speed of the boat (through the water) 'B'.
Call the speed of the current (the water) 'C'.

When the boat is going 'up' the river, against the current,
his speed past the riverbank is (B - C).

When the boat is going 'down' the river, the same way as the current,
his speed past the riverbank is (B + C).

The problem says it took him 5 hours to travel 60 km against the current.
Distance = (speed) x (time)
60 km = (B - C) x (5 hours)

The problem also says it took him 3 hours to return.
The distance to return is the same 60 km.
The other direction is the same direction as the current,
so his speed on the return is (B + C).
Distance = (speed) x (time)
60 = (B + C) x (3)

Now we have two equations, so we can find 'B' and 'C'.

5B - 5C = 60
3B + 3C = 60

Multiply each side of the first equation by 3, and
multiply each side of the second equation by 5:

15B - 15C = 180
15B + 15C = 300

Add the second equation to the first one:

30B = 480
B = 480/30 = 16 km per hour.

Subtract the second equation from the first one:

-30C = -120
C = -120/-30 = 4 km per hour.

The speed of the boat through the water (B) is 16 km per hour.
The speed of the water past the riverbank is 4 km per hour.

Check:

-- When the boat is going along with the current, his speed past the riverbank
is (16 + 4) = 20 km per hour. In 3 hours, he covers (3 x 20) = 60.

-- When the boat is going against the current, his speed past the riverbank
is (16 - 4) = 12 km per hour. In 5 hours, he covers (5 x 12) = 60 km.

X²-3x=0
Solve by factoring
I know that x=0,3, but how do you get that from x(x-3)=0?

Answers

by equating each factor by 0
x*(x-3)=0
so, x=0 & x-3=0
x=0 & x=3

You have to solve the equation by essentially taking out the parentheses. So you will take x, which is outside the parentheses and multiply it by each factor inside of them.

So you will multiply x with x (first term in brackets) and multiply x with 3, second term in the bracket. You will then add these two terms together.

Solve.: -2 1/3 -(-5) A:-7 1/3 B: 2 2/3 C: 3 2/3 D: 3 1/3

Answers

Step-by-step explanation:

-2 1/3 -(-5) can be simplified as follows:

-2 1/3 + 5

= -7/3 + 15/3 (converting mixed numbers to improper fractions)

= 8/3

Therefore, the solution is 8/3, which can also be expressed as 2 2/3.

So, the answer is (B) 2 2/3.

What is 7% of 120 is

simplify

Answers

7% of 120 is 8.4

Change the percentage into a decimal by dividing it over 100:

7 / 100 = 0.07

Multiply:

0.07 × 120 = 8.4

7% of 120 is:
0.07 x 120
=42/5
=8.4

Let's take the original price as a
After the discount of 20%, the price is 250.
80/100 * a = 250
a = 250 * 100 / 80
a = 312.5

So original price is 312.5
