David cuts a 6 metre long pole into three different pieces. The largest piece is 40 cm longer than the middle piece. The middle piece is 70 cm longer than shortest piece. What is the size of the largest piece?

Answer 1

x = shortest piece

x + x + 70 + x + 110 = 600

3x + 180 = 600

3x = 420

x = 140

Middle piece = 210

Longest piece = 250
