2 90
3 135
5 225
6 270
Find the constant of proportionality.

Use the constant of proportionality to write a unit rate for the data in the table.

Write an equation to represent the relationship between time, t, and distance, d.

1 answer

The constant of proportionality is 45 (distance divided by time).

The unit rate is 45 miles/hour.

The equation to represent the relationship between time, t, and distance, d, is d = 45t.
