Question

If a length of pipe measures 10 metre, how many lengths of pipe will be needed to lay 2 km of pipe?

Answer 1

Answer:

length of pipe = 10 m.

1 km = 1000 m

2 km = 2000m

length for 2 km = 2000 × 10 = 20000m.

Answer 2

Here the length of 1 pipe is given to be 10 meter

We have to find out the number of pipes that will be needed to lay a 2 km pipe

First, we will convert 2 km into m

2 km = 2 × 1000 m

        = 2000 m

Number of pipes needed = 2000/10

                                          = 200

Hence, 200 pipes will be needed
