A worker uses 560 inches of steel wire to make 350 springs of the same size. At this rate how many inches of steel wire are needed to make 1 spring?

1.5 inches of steel

Step-by-step explanation:

450/300

=1.5 in.

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.
