Question

Maya cut a 6m piece of string in 3 different piece.The longest piece is 40cm longer than the middle piece.The middle piece 70cm longer than the shorter piece. How long is the longest piece in cm

Answer 1

Answer:

length of longest piece is 250 cm

step by step explanation

let shorter piece be x

middle piece be 70+x

longest piece be 40+length of middle piece

=40+70+x

length of total string = 6m =600cm

sum of all parts of a string =600cm

x +70+x+40+70+x = 600

3x+180 = 600

3x = 600 - 180

3x = 420

x = 420/3

x = 140

shorter piece = 140cm or 1.4 m

middle piece = 70+x = 70+140 =210 cm

longest piece. = 40 +70+x=250cm

Therefore the length of longest piece is

250cm
