A piece of ribbon folded five times is placed along a 30 cm long measuring scale as shown in Fig.
The length of the ribbon is between.
A. 1.15 m - 1.25 m
B. 1.25 m - 1.35 m
C. 1.50 m - 1.60 m
D. 1.60 m - 1.70 m
Given: A ribbon folded 5 times
To find: The length of the ribbon
Solution:
The folded ribbon lies between 2 cm and 27.5 cm. So its length is the distance between 2 cm and 27.5 cm.
It is 27.5 - 2 = 25.5 cm.
The length of the folded ribbon is nearly 25.5 cm.
Since it is folded 5 times, the total length of the ribbon is about 5$\times$25.5 cm = 127.5 cm
= 1.275 m . (100 cm = 1 m)
The correct answer is (b) 1.25 m−1.35 m.
