Question

The length of a rope is 20.6 m. How many pieces will there be,
if each piece is 1.2 m long? Round off your answer to 2 d.p.​

Answer 1

Step-by-step explanation:

Length of the rope = 20.6 meters.

Assume length of longer piece = x meters.

Length of shorter piece = x - 2.8

We know that x + x - 2.8 = 20.6

2x = 23.4

Length of the longer piece = x = 11.7 meters

Correct Option: E

Answer 2

Answer:

17.17 or 18 pieces

Step-by-step explanation:

Length of a rope = 20.6 m

Let x be the total number of pieces of the rope 1.2 m long

1.2x = 20.6

x = 20.6/1.2 = 17.16667 ≈ 17.17 = 18 pieces
