The video tutorial covers classwork on related quantities, focusing on constant speed, writing distance equations, interpreting graphs, solving power equations, and finding equivalent expressions. It also includes an analysis of a walkathon scenario to identify independent and dependent variables.

If a car travels at a constant speed of 50 miles per hour, how far will it travel in 3 hours?

• 150 miles

• 100 miles

• 250 miles

• 200 miles

What is the equation to calculate the distance D traveled by a car moving at a constant speed of 50 miles per hour for time T?

• D = 50 - T

• D = T/50

• D = 50T

• D = 50 + T

On a graph showing time and distance, what does the point (25, 0.5) represent?
