Answer:
The height of the pan is 2 inches.
Step-by-step explanation:
Given : Paul bags of raisin bars in a pan shaped like a rectangle or prism the volume of the pan is 252 in.³ the length of the pants 12 inches and it's with is
inches.
To find : What is the height of the pan ?
Solution :
The volume of a rectangle or prism is
![V=l\times w\times h](https://tex.z-dn.net/?f=V%3Dl%5Ctimes%20w%5Ctimes%20h)
Where, l=12 inches is the length
inches is the width
V=252 in.³ is the volume
h is the height
Substitute the value,
![252=12\times 10\frac{1}{2}\times h](https://tex.z-dn.net/?f=252%3D12%5Ctimes%2010%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20h)
![252=12\times \frac{21}{2}\times h](https://tex.z-dn.net/?f=252%3D12%5Ctimes%20%5Cfrac%7B21%7D%7B2%7D%5Ctimes%20h)
![h=\frac{252\times 2}{12\times 21}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B252%5Ctimes%202%7D%7B12%5Ctimes%2021%7D)
![h=2](https://tex.z-dn.net/?f=h%3D2)
Therefore, the height of the pan is 2 inches.
Let's call your speed "a"
her walking speed is then "2a"
and her friend's scooter speed is 10 a
let's also call the distance you need to walk "d"
so the time (t)you need is:
d/t=a
t=d/a
and her time is:
t=
![\frac{d}{2} /2a+ \frac{d}{2} /10a](https://tex.z-dn.net/?f=%20%5Cfrac%7Bd%7D%7B2%7D%20%2F2a%2B%20%5Cfrac%7Bd%7D%7B2%7D%20%2F10a)
(half a distance with the speed of 2a and half a distance (d/2) with the distance of 10 a
now we count (we know that her time is 30 minutes)
30=
![\frac{d}{4a}+\frac{d}{20a}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bd%7D%7B4a%7D%2B%5Cfrac%7Bd%7D%7B20a%7D)
//multiply by 20a
600a=
![5d+d](https://tex.z-dn.net/?f=%205d%2Bd)
600a=6d/divide by 6
100a=d
Now, in order to calculate your time we need to calculate:
t=d/a
but we know how much is d now!
t=
![\frac{100a}{a}](https://tex.z-dn.net/?f=%20%5Cfrac%7B100a%7D%7Ba%7D%20)
=100
which means that you need 100 minutes, or 1 h 40 minutes!!!
