Question

If t varies as v, and t = 2 4/7 when v = 13/14 , find v when t = 2 1/4.
v=
Direct variation

Answer 1

direct variation:
v = kt, where k is a constant
plug in the given v and t to solve for k

13/14 = 18/7 k

k = 13/36

--> v = 13/36 t
now plug in any t to find the resulting v

Answer 2

do I multiply 18/7 by 13/36?

Answer 4

gawd I feel like I'm insulting you...

Answer 5

use the unitary method
t v
24/7 13/14
21/4
hence v={(13/14)/(24/7)}*(21/4)
v=19/64
