Boats: key points

Boat and stream questions compare the speed in still water with the speed of the current.

  • Downstream speed = still-water speed + stream speed.
  • Upstream speed = still-water speed − stream speed.
  • Still-water speed is half the sum of downstream and upstream speeds.

How to practise Boats

Start with the key points, then take one Boats test without rushing. Review every explanation, note the steps you missed and repeat the topic against the clock. APTITUDE TESTER has 20 questions in 2 tests for this topic.

  • Read the method before attempting a timed test.
  • Record mistakes by type: concept, calculation or time management.
  • Return to the hardest questions after a day and try them again.

Continue with another Quantitative topic when your accuracy is steady.

Sample Boats questions

  1. 1. A boat moves downstream at 13 km/h. How long will it take to cover 56 km?
    1. 3.81
    2. 4.31
    3. 5.81
    4. 2.81

    Answer: B. 4.31

    Downstream speed is 13 km/h, so time = distance / speed = 56 / 13 = 4.31 hours.
  2. 2. A boat moves upstream at 9 km/h. How long will it take to cover 85 km?
    1. 7.94
    2. 9.44
    3. 10.94
    4. 10.44

    Show answer and solution

    Answer: B. 9.44

    Upstream speed is 9 km/h, so time = 85 / 9 = 9.44 hours.
  3. 3. A boat travels downstream at 23 km/h and upstream at 8 km/h. Find its speed in still water.
    1. 17.5
    2. 14.5
    3. 15.5
    4. 18.5

    Show answer and solution

    Answer: C. 15.5

    Still-water speed is the average of downstream and upstream speeds: (23 + 8) / 2 = 15.5 km/h.
