Study the following information carefully and answer the given questions. Five ships (A, B, C, D, and E) are moored at Dock M, and their captains (P, Q, R, S, and T) are steering their respective ships. Each ship starts from the dock, moves in a specific direction, and covers a certain distance before reaching its final position which is named as ship's captain's name. Movements of the ships: I. Ship A, steered by Captain P, starts moving north and covers 5m, then turns left and moves 8m, finally turning right and moving 10m to reach its final position. II. Ship B, steered by Captain Q, moves east for 12m, then turns right and moves 7m, finally turning right again and moving 3m to its final position. III. Ship C, steered by Captain R, starts by moving south for 6m, then turns right and moves 5m, then turns left and moves 9m to its final position. IV. Ship D, steered by Captain S, moves west for 10m, then turns left and moves 4m, finally turning right and moving 6m to its final position. V. Ship E, steered by Captain T, starts moving north for 8m, then turns right and moves 10m, finally turning right again and moving 5m to its final position. What is the total distance covered by Q and R in their journey?

Answer
Correct Answer: 42m
Explanation
### Concept & Distance Calculation
The total distance covered by a ship is the simple arithmetic sum of all the individual straight-line segments it travelled, regardless of the direction.
### Step-by-Step Solution
* **Distance covered by Q (Ship B):** It moves 12m, then 7m, then 3m. Total distance = $12 + 7 + 3 = 22\text{ m}$.
* **Distance covered by R (Ship C):** It moves 6m, then 5m, then 9m. Total distance = $6 + 5 + 9 = 20\text{ m}$.
* **Total combined distance:** Sum the individual distances: $22\text{ m} + 20\text{ m} = 42\text{ m}$.
### Exam Strategy & Shortcut
For "total distance covered" (not shortest distance/displacement), simply scan the text for the numbers associated with the specific ships and add them up. You do not need to deduce directions at all.
### Common Pitfall
Confusing "total distance" with "shortest distance" (displacement) from the starting point.
### Final Answer
Therefore, the correct answer is **42m**.
