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.

D is an example. As stated above, questioning source information is great, but then you need to also verify it, because, like said before, not everything is true.
