Which of the following represents the most accurate estimation of 54 - 16?

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

answer: answer is b.

[m < b = 120º]
