Step-by-step explanation:
Proportional functions can be represented by , where
is a constant of proportionality and
represents any point the line passes through.
In the graph, we can see the line passes through (20, 40). Therefore, we can plug in these coordinates to find the constant of proportionality:
Answer:
calories
Step-by-step explanation:
Given: The racer moves at miles per hour expends energy at a rate of
calories per hour.
To find: Energy in calories, required to complete a marathon race miles at this pace.
Solution: We have,
The racer moves at miles per hour.
The racer expends energy at a rate of calories per hour.
So, energy expended while moving miles
calories.
Now, energy expended while moving mile
calories.
So, energy expended while moving miles
calories.
Hence, calories of energy is required to complete a marathon race
miles at this pace.
