The time taken to get to the 4th can be obtained by dividing the distance given by the speed of the lift.
Distance, height from ground to 4th floor = 42 feets
Time taken to get to the 4th floor = t
Recall :
Time = Distance / speed
- We aren't given the speed of the lift ;
- Assume speed of lift is 7 ft/sec
The time taken to get to the 4th floor will be :
Therefore, to obtain the time taken, divide the distance or height of the 4th floor by the speed of the lift.

Using proportions, it is found that the total volume of the glass is of 216 cm³.
<h3>What is the missing information?</h3>
The problem is incomplete, but researching it on a search engine, it is found that:
- Initially, the glass is 1/3 full.
- After adding 63 cm³ of orange of juice, the glass is 5/8 full.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
Considering the volume of the glass as x, and the information given in the problem, the following equation can be built:
We solve for x to find the volume of the glass as follows:
Then, applying cross multiplication:
7x = 24 x 63
Simplifying by 7:
x = 24 x 9
x = 216 cm³.
The total volume of the glass is of 216 cm³.

If the perimeter is 16, the side length is 4 units.
To find the area of the shaded sections, you will use the fractional part that each section represents and multiply that fraction by the total area of the square.
Area of DEA is 1/4 of 16 square Units (4 x 4).
1/4 x 16 = 4 square units
Area of EFB is 1/8 of 16 square units.
1/8 x 16 = 2 square units
4 square units +2 square units equals 6 square units.
The area of the shaded region is 6 square units.
