Do you know that rate multiplied by time = distance?

- anonymous

yesss

- Mertsj

Then find how long it took to go 20 km downstream.

- Mertsj

How far downstream did she go?

- anonymous

20km

- Mertsj

|dw:1377828382982:dw|

- Mertsj

That is distance. Replace distance with 20

- Mertsj

How fast was she traveling downstream?

- anonymous

10km/h

- Mertsj

That is the rate. Replace rate with 10. Find the time.

- anonymous

10x=20 ?

- Mertsj

|dw:1377828552953:dw|

10 is answer?

- Mertsj

So do you really think that 10 times 10 = 20 or are you just being a smart aleck?

- anonymous

noo )': I said 10t=20
10t/10=20/10
t=10 10=answer? im not being cocky )'; )';

- Mertsj

Do you really think that 20 divided by 10 is 10?

- anonymous

ohh 2. my bad.. a yeah I did.. jeezz

- Mertsj

2 what?

- anonymous

please help w/5 more? 2pm

- Mertsj

2 hours. It took her 2 hours to go 20 km downstream because she was traveling 10 km each hour so it took her 2 hours to go 20 km.

- Mertsj

She left at noon. So now she is 20 km downstream and it it 2 pm.

- anonymous

it says what time did she arrive back at the landing, what time

- Mertsj

Now she has to go back. So she has to travel 20 km again. How fast is she going this time?

- anonymous

20(2)?

- Mertsj

Read the problem. How fast is she going on the return trip?

- anonymous

20(4)?

- Mertsj

So you are saying she is traveling 80 km per hour on the return trip?

- anonymous

20/4?

- Mertsj

Why can't you do the same thing you did before and replace distance with 20 and rate with 4 and solve for time?

- anonymous

5

- anonymous

I got 5 doing it how u just said

- Mertsj

5 what?

- anonymous

2pm,5pm

- anonymous

???????? is it 2pm, 5pm? @Mertsj

- Mertsj

I thought you were solving for time?

- Mertsj

If you leave at noon and you travel for 2 hours and then you turn around and travel for 5 more hours, what time is it now?

- anonymous

7 pm

- anonymous

?

- Mertsj

yep

- anonymous

so 5pm, 7pm?

- anonymous

my bad I meant. 2pm, 7pm?????

- Mertsj

How long did it take her to get 20 km downstream?

- anonymous

5pm,7pm???

- Mertsj

rt=d
10t=20
t=2 hours
She left at noon. She traveled 2 hours to get 20 km downstream.
It is now 2 pm
She turned around at 2 pm
rt=d
4t=20
t=5 hours
She turned around at 2 pm. She traveled for 5 hours to get back.
It is now 7 pm

- Mertsj

I have noticed that you have a real problem answering the question you are asked. Reread this discussion and notice how many questions I asked you that you answered with something other than the answer to that specific question. That same problem caused you to be unable to answer the question the problem asked even after you had it solved. If you focus on answering the EXACT question you are asked, it will be a help to you.

9.) At 10:30 a.m. two planes leave Houston, one flying east at 560 km/h and the other flying west at 640 km/h. at what time will they be 2100 km apart?

- Mertsj

The distance of the first plane is 560t
The distance of the second plane is 640t
The sum of the two distances must be 2100
Write and solve that equation.

- anonymous

560+640=2100

- Mertsj

What is the distance of the first plane?

- Mertsj

The distance of the first plane is 560t

- Mertsj

What is the distance of the first plane?

- anonymous

560t +640t=2100
1100t=2100
1100t/1100=2100/1100
x=

- anonymous

is it set up like that?

- Mertsj

Yes. But 560 +640 is not 1100

- anonymous

1200
