Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
The graph shows the speed of a vehicle. Find the speed in kilometers per minute.
![### Vehicle Speed
#### Graph Description
This graph illustrates the relationship between time and distance traveled, representing vehicle speed. The x-axis (horizontal axis) denotes time in minutes, and the y-axis (vertical axis) represents distance in kilometers.
#### Explanation of Axes
- The x-axis (Time) is labeled from 0 to 2 minutes, with increments of 1/2 minute.
- The y-axis (Distance) is labeled from 0 to 2 kilometers, with 1/2 kilometer increments.
#### Data Points
Two specific data points are highlighted and labeled on the graph:
1. **(1, 1/4)**: This point indicates that after 1 minute, the vehicle has traveled 1/4 kilometer.
2. **(2, 1/2)**: This point indicates that after 2 minutes, the vehicle has traveled 1/2 kilometer.
#### Line Description
A straight line connects these points, illustrating a consistent speed over the given time interval. The slope of the line indicates the vehicle's speed.
The graph provides a visual representation of the relationship between time and distance for vehicle speed, indicating that the vehicle travels at a uniform rate.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb3a77f83-4371-4ed7-8036-da6df02d6502%2F5cd18d46-5a63-4a93-b0fd-96643acf5b8c%2Fxvwj3v_processed.png&w=3840&q=75)
