A worker uses 450 inches of steel wire to make 300 springs of the same size. At this rate how many inches of steel wire are needed to make 1 spring?
1/3 Inch
1/15 inch
2/3 inch
1 1/2 inch
To find out how many inches of steel wire are needed to make 1 spring, we simply need to divide the total amount of steel wire used (450 inches) by the number of springs made (300 springs).
450 inches / 300 springs = 1.5 inches
Therefore, 1.5 inches of steel wire are needed to make 1 spring. The correct answer is 1 1/2 inch.
