Question

three pieces of ropes measuring 0.2 km, 5005 CM and 1200 mm respectively are joined end to end to form a single rope. How long is the new rope​

Answer 1

Answer:

251.25 m

Step-by-step explanation:

Since all the given dimension are of different units, lets first convert them to the standard unit of m.

First rope = 0.2 km = 200 m

Second Rope = 5005 cm = 50.05 m

Third Rope = 1200 mm = 1.2 m

Therefore the new rope is combination of all these small ropes. Hence the length of the new rope would be:

⇒ 200 m + 50.05 m + 1.2 m

⇒ 251.25 m

Therefore the length of the new rope is 251.25 m or 2.5125 km.

Answer 2

Answer:

Step-by-step explanation:

Given :-

Changing all the dimensions to standard unit of meter. Because all dimension are in different units.

1st Rope Measurement = 0.2 km = 200 m

2nd Rope Measurement = 5005 cm = 50.05 m

3rd Rope Measurement = 1200 mm = 1.2 m

To Find :-

Total length of new rope

Formula to be used :-

Combining (adding) all the ropes dimensions.

Solution :-

Putting all the values, we get

⇒ Total Length = 1st Rope + 2nd Rope + 3rd Rope

⇒ Total Length = 200 m + 50.05 m + 1.2 m

⇒ Total Length = 251.25 meter

Hence, the length of new rope is 251.25 meter.
