Solution

The correct option is B 18 minutes
Storage tank 3 is at (5, -3).

Storage tank 4 is at (-4, -3).

To reach storage tank 4, you have to move 9 units in the left direction.

As it takes 2 minutes per block, total time will be, number of blocks $\times$ 2 minutes.

Total number of blocks = 9

Total time taken = 9 $\times$ 2 = 18

Hence, the total time taken to move from storage tank 3 to storage tank 4 is 18 minutes.
