A wood board 250 centimeters long is cut into five pieces: three short ones of equal length and two that are both 15 centimeters longer than the shorter ones. What are the lengths of the boards?

x = three length

 

x + x + x     +   x+15    + x+15   = 250

5x +30 = 250

5x = 220

x = 44    x+15 = 59 cm
