If time t increases by 1 second, by how much does the distance dchange? How is this change represented in a table? In a graph?2. If t increases by 5 seconds, by how much does d change? How is thischange represented in a table? In a graph?3. What is the walking rate per minute? The walking rate per hour?Alana : 1 meter per secondGilberto: 2 meters per secondLeanne : 2.5 meters per second

Answer 1

The relationship between the time and the distance walked is an illustration of a linear equation.

The change in distance when time increases by 1 second

From the table, we have the following equations:

• Alana: y = x
• Gilberto: y = 2x
• Leanne: y = 2.5x

The above equations mean that if time t increases by 1 second,

• Alana's distance increases by 1 meter
• Gilberto's distance increases by 2 meters
• Leanne's distance increases by 2.5 meters

The change in distance when time increases by 5 seconds

When time increases by 5 seconds, the rate is multiplied by 5

This means that:

• Alana's distance increases by 5 meters
• Gilberto's distance increases by 10 meters
• Leanne's distance increases by 12.5 meters

The walking rate per minute

The walking rate per minute is the unit rate or slopes of the linear equations.

So, the walking rates per minute are:

• Alana's walking rate = 60 meters per minute
• Gilberto's walking rate = 120 meters per minute
• Leanne's walking rate = 150 meters per minute
