D=KT K=45

3. Pandalover485 Group Title

m confse can u showme step by step

4. Hope_nicole Group Title

you have to find the common change

5. Notamathgenius Group Title

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

d=45t ???

10. lstrasmann Group Title

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

11. Pandalover485 Group Title

45

12. lstrasmann Group Title

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

13. Pandalover485 Group Title

is tht all?

14. Pandalover485 Group Title

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

15. lstrasmann Group Title

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. lstrasmann Group Title

or would it be 45/1?

17. lstrasmann Group Title

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. Pandalover485 Group Title

IT WOULD BE 1/45 RIGHT

19. Pandalover485 Group Title

srry caps

20. lstrasmann Group Title

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