Time (hours). distance (miles)2. 90 3. 135 5. 2256 . 270a. find the constant of proportionalityb. use the constant of proportionality to write a unit rate for the data in the table. c. write an equation to represent the relationship between time, t, and distance, d.

A) 90 / 2 = 45

135 / 3 = 45

225 / 5 = 45

270 / 6 =45

The constant of proportionality is 45

B) The unit rate would be 45 miles per hour

C) The equation would be to multiply the constant ( 45 miles per hour) by the time ( number of hours) to get the total distance:

D = 45t

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
