To solve for this we will be using the formula S = D/T
S = Speed
D = Distance
T = Time
First we need to re-arrange this formula to solve for time
T= D/S
T = 400/230
T=1.74 hours
.74 hours is close enough to .75 that we can say it is 45 minutes
So it is 1 hour and 45 minutes
Answer + Explanation:
let x be the measure of angle x
let y be the measure of angle y
![\left \{ {{x + y = 180} \atop {x=24+y}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7Bx%20%2B%20y%20%3D%20180%7D%20%5Catop%20%7Bx%3D24%2By%7D%7D%20%5Cright.)
Now, solve:
plug x = 24 + y into x + y = 180
24 + y + y = 180
24 + 2y = 180
2y = 156
y = 78
Now, plug this back into the equation x = 24 + 78
x = 102

Answer:
585 cars
Step-by-step explanation:
Given
![Floors = 5](https://tex.z-dn.net/?f=Floors%20%3D%205)
per floor
Required
Determine the total number of cars
This is calculated by multiplying number of cars per floor by number of floors.
![Total = Floors*Cars](https://tex.z-dn.net/?f=Total%20%3D%20Floors%2ACars)
![Total = 5 * 117](https://tex.z-dn.net/?f=Total%20%3D%205%20%20%2A%20117)
![Total = 585](https://tex.z-dn.net/?f=Total%20%3D%20585)
<em>Hence, there are 585 cars in total</em>
