<span>Welding rods are necessary in the welding process to add filler metal to the area being welding. In some arc welding methods the welding rod is also used as the electrode. The welding rod is typically made of the same material that the base metals are made of and a flux is often used to help with the welding process being used. Welding rods are typically held by an electrode holder that is used to insulate the welder from the electric current created from the welding process.

Given that,
He walks at 3 km/hour.
If the container ship is 100 m long, and travelling at 12 km/hour.
The distance will be 200 m.
We need to calculate the relative velocity
Using formula of relative velocity
Put the value into the formula
The distance is 200 m.
We need to calculate the time
Using formula of time
Put the value into the formula
Hence, The time of oil tanker will be 80 sec.
