Q:

I NEED HELP ASAP!!!Use the tables to answer the following questions. a. find the constant of proportionalityb. use the constant of proportionality to write a unit rate for the data in the tablec. write an equation to represent the relationship between time, t, and distance, d.time distance(hours) (miles)2 903 1355 2256 270

Accepted Solution

A:
Answer:a. The constant = 45b. The unit rate is 45 miles per hourc. d = 45tStep-by-step explanation:a. ∵ d ∝ t∴ d = kt∵ d = 90 at t = 2∴ 90 = k(2)∴ k = 90 ÷ 2 = 45∴ The constant of proportionality is 45b. ∵ k = d(miles) ÷ t(hours) = 45∴ The unit rate is 45 miles per hourc. The equation is ⇒ d = 45t
