    Biomass conversion
    This document contains 7 word problems about boats traveling with and against stream currents. It asks the reader to calculate speeds of boats, streams, distances traveled, and times taken based on information provided about trips upstream and downstream. The problems get progressively more complex, asking the reader to use multiple pieces of information provided in each problem to determine values like stream speed, boat speed, and travel distances or times.

    BOAT AND STREAM

    1. A man's speed with the current is 15 km/hr and the speed of the
    current is 2.5 km/hr. The man's speed against the current is:
    A. 8.5 km/hr B. 10 km/hr.
    C. 12.5 km/hr D. 9 km/hr

    2. A boatman goes 2 km against the current of the stream in 2 hour


    and goes 1 km along the current in 20 minutes. How long will it take
    to go 5 km in stationary water?
    A. 2 hr 30 min B. 2 hr
    C. 4 hr D. 1 hr 15 min

    3. A motorboat, whose speed in 15 km/hr in still water goes 30 km


    downstream and comes back in a total of 4 hours 30 minutes. The
    speed of the stream (in km/hr) is:
    A. 10 B. 6
    C. 5 D. 4

    4. A man rows to a place 48 km distant and come back in 14 hours.


    He finds that he can row 4 km with the stream in the same time as 3
    km against the stream. The rate of the stream is:
    A. 1 km/hr. B. 2 km/hr.
    C. 1.5 km/hr. D. 2.5 km/hr.
    BOAT AND STREAM

    5. A man takes twice as long to row a distance against the stream as


    to row the same distance in favour of the stream. The ratio of the
    speed of the boat (in still water) and the stream is:
    A. 3 : 1 B. 1 : 3
    C. 1 : 2 D. 2 : 1

    6. A boat takes 38 hours for travelling downstream from point A to


    point B and coming back to point C midway between A and B. If the
    velocity of the stream is 4 kmph and the speed of the boat in still
    water is 14 kmph, what is the distance between A and B?
    A. 240 km B. 120 km
    C. 360 km D. 180 km

    7. A motorboat travelling at the some speed, can cover 25 km


    upstream and 39 km downstream in 8 h. At the Same speed, it can
    travel 35 km upstream and 52 km downstream in 11 h. The speed of
    the stream is

    A) 2 km/h

    B) 3 km/h

    C) 4 km/h
    BOAT AND STREAM

    D) 5 km/h
