sin 0

and tan x when x =0

will provide a value of 0

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

the answer is 15.50 for one mile

b) is slope: 0   y- intercept 15.5
