Question

Isabella drives at a constant 45 miles per hour is she drives for why miles and it takes her X hours what is the two variable equation to represent the number of miles isabella Drive Annex hours

Answer 1

Required two variable relation is 45x =y

Explanation:

Speed of isabella car is v = 45 miles per hour

now, According to question she takes Y miles( = distance) in X hours (= time)

from The relation of velocity i.e.

velocity =
`(distance)/(time )`

on substituting the values in the above relation we get,

v = 45 =
`(y)/(x)`

on further rearranging of terms we get,

`45x` = y

HENCE, required relation is 45x =y , which is a two variable equation.
