## anonymous 3 years ago Find the constant of proportionality and the unit rate for the data in the table. Then write an equation to represent the relationship between time t and distance d. time and distance table

D=KT K=45

3. anonymous

m confse can u showme step by step

4. anonymous

you have to find the common change

5. Notamathgenius

The best I can say is you need to divide them, 90/2=45

d=45t ???

10. anonymous

If you divide each of them, what is the number you get each time?

11. anonymous

45

12. anonymous

Good. So that is the common change that @Hope_nicole was talking about.

13. anonymous

is tht all?

14. anonymous

I have a f in math im sooooooooooooo confuse...

constant of proportionality - the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality $90 = 2k$$135 = 3k$etc, etc So we know that 45 is the factor of proportionality, which is the first part of your problem. The unit rate is one over the factor of proportionality, so it would be 1/45 (45 miles per hour)

16. anonymous

or would it be 45/1?

17. anonymous

Yes, it is 45/1$\frac{ 45 miles }{ 1 hour }$ So now all you have to do is write an equation representing the rate.

18. anonymous

IT WOULD BE 1/45 RIGHT

19. anonymous

srry caps

20. anonymous

No, it is 45/1. I made a mistake.
