Question

Let x represent the time in minutes and let y represent the distance in feet. This table shows the relationship between time (in minutes) and distance (in feet).


Relationship Between Time and Distance

Time (Minutes), x

1 2 3 4
Distance (Feet), y

75 150 225 300
Use the table to create a formula for the given information.

Answer 1

y = 75x

(Each minute adds 75 feet, so the constant of proportionality is 75: y varies directly with x.)
