Question

Write a direct variation equation that relates x-miles and y- kilometers.

Answer 1

Answer:

$y=1.60934x$

Step-by-step explanation:

If x is directly proportional to y, then

$y\propto x$

$y=kx$

where, k is constant of proportionality.

We know that,

1 miles = 1.60934 km

It is given that x-miles and y- kilometers. Constant of proportionality is 1.60934.

$y=1.60934x$

Hence, the required equation is $y=1.60934x$.
