Question: A certain machine produces 1,000 units of product P per hour. Working continuously at this constant rate, this machine will produce how many units of product P in 7 days?
- 7,000
- 24,000
- 40,000
- 100,000
- 168,000
Correct Answer: E
Solution and Explanation:
Approach Solution 1:
The problem statement states that:
Given:
- A certain machine produces 1,000 units of product P per hour.
- the machine is working continuously at this constant rate.
Asked:
- To find the number of units of product P in 7 days.
A specific machine can produce 1,000 units in one hour.
As a result, the machine can produce 24,000 units in 24 hours.
In other words, the machine can produce 24,000 units in a single day.
As a result, the machine can produce (24,000)(7) units in 7 DAYS.
Which is
24000 * 7 = 168,000
This machine will produce 168,000 units of product P in 7 days
Approach Solution 2:
There is another approach to solve this question which is simple and easy.
7 days equals 24 * 7 hours = 168 hours.
Because the machine produces 1000 units of product P every hour,
The total product over 168 hours is equal to 1000 x 168 = 168,000.
this machine will produce 168,000 units of product P in 7 days
