Question

Francis delivers 440 pamphlets in 2 hours and earns $5 per 100 pamphlets delivered.

How long will it take Francis to earn $55?

Answer 1

@waterineyes

Answer 2

For earning $55 he will have to deliver : \(11 \times 1100 = 1100\)


In 2 hours he delivers : 440

How much time will it take to deliver 1100 pamphlets, that we have to find..

Answer 3

440 pamphlets can be delivered in : 2 hours:

So:

1100 pamphlets will be delivered in : \(\frac{2}{440} \times 1100 = 5\).

So in my view 5 hours it will take..

Answer 4

ur first part shouldn't it be 11 x 100 = 1100 not 11 x 1100 = 1100?

Answer 5

Oh my mistake..

Wait a minute..

Answer 6

That will be 11 times 100 = 1100..

Answer 7

and wat does the 11 represent?

Answer 8

For earning $55 he will have to deliver : \(11 \times 100 = 1100\)..

Answer 9

Let me explain..

Answer 10

5 dollars he earns for : 100 pamphlets

1 dollar he earns for: \(\frac{100}{5} = 20\) pamphlets

So 55 dollars he will earn for : \(20 \times 55 = 1100\)

Answer 11

Getting now ??

Answer 12

So then you have to find how much will it take to deliver 1100 pamphlets..

Are you getting or not @JayDS

Answer 13

yep.

Answer 14

and why is it 2/440 for the second part?

Answer 15

See:

440 pamphlets can be delivered in : 2 hours

So if you want to find delivery of 1 pamphlet you will divide both sides by 440..

So:

\[\frac{440}{440} \; pamphlets \; In \; \frac{2}{440} \quad hours\]

Getting ??

Answer 16

So:

1 pamphlet can be delivered in : \(\frac{2}{440}\)

and for 1100 you will multiply both the sides by 1100..


\(1 \times 1100\) pamphlets can be delivered in : \(\frac{2}{440} \times 1100 = 5\)

Now is it clear to you ?

Answer 17

the 2/440 is still a bit confusing.

Answer 18

440 pamphlets can be delivered in : 2 hours

this much is clear to you or not ??

Answer 19

yes

Answer 20

Write it like simple equation:

440x = 2y ( x represents pamphlets and y represents hours)

Now to find x what will you do ??

Answer 21

isolate x
so x = 2y/440

Answer 22

That is what I did there..


So I can write it as:

1x = 2/440 y

Now clear to you ??

Answer 23

replace here x any y:

1 pamphlet = 2/440 hours..

Answer 24

ok, I think so, I will have to write all of it in sequence first.

Answer 25

Sure..

Answer 26

you can help others if you want to, and thanks

Answer 27

Okay..

Take your time..
