Question
10 ropes of length 1.25 m are joined together. What is the length of the new rope? Explain and name the postulate you used.
Hint:
First consider price of 1 rope and then multiply with no. of ropes to get total length.
- Step by step explanation:
- Given:
Length of rope = 1.25m.
No. of rope = 10
- Given:
The correct answer is: 12.5m.
Step 1:
- Calculate the length of new rope:
Length of 1 rope = 1.25m
So, length of 10 ropes = 1.25 × 10
= 12.5m
Hence, the length of new rope is 12.5m.
