  1. (1*18/5) = 3.6kmph
    1mps = 3.6kmph
    14mps * 3.6kmph = 50.4kmph

  2. 1 m/s = 3.6 km/hr
    14 m/s x 3.6 = 50.4 Km/hr

    Option B is Correct

  3. 1 m/s = 3.6 km/hr
    14 m/s x 3.6 = 50.4 Km/hr

    Option B is Correct

  4. 1 SEC 14 MTR
    1 MINURE 840 METER
    1 HOUR IS 840 *60 = 50.400MTR
    ANS IS B 50.4KM/HR

  5. 1 sec = 1/3600 hr
    1 meters = 1/1000
    So,
    (14/1000)÷(1/3600)= 50.4 km/hr

  6. 1 second = 14 meters
    1 minutes = 14×60 (1 min = 60sec)
    = 840 meters
    1 hour = 840 ×60
    = 50400 meters (1hour = 60 minutes)
    50.4 km/h

  7. 14m/s * 60seconds*60 minutes / 1000= 50.4km/hr

  8. Given speed = 14 m/s
    To change m/s to km/hr we can multiply the speed with 18/5
    14*(18/5) = 50.4 km/hr

    As we know
    1km = 1000 m
    And 1hr = 3600 sec
    So 1km/hr = 1000/3600 m/s
    = 5/18 m/s

  9. 14 metres/second is your query

    by logical deduction, 1 metre per second equals 3600 metres/HOUR

    3600 is your operative

    move the decimal over to the left 3 places (thousandths) ↩️↩️↩️

    This gives you 3.6

    Now multiply 3.6×14 = 50.4

    Good mathematical exercise

  10. 50.4km/hr
    14 meter/s
    1min =60second
    1000meter = 1 km
    14*60= 840meter in one mint
    60min = 1 hour
    So, 840*60 =50400meter
    50400/1000 = 50.4km/h

  11. 50.4 km/hr (explainantion : 1 min = 60 sec & 60 min= 1 hr 14 * 60 sec= 840 meters & 840*60 min = 50400 meters , now 1 km = 1000 m ,so 50400/1000 = 50.4 km/hr

  12. B) 50.4km/hr
    1km=1000m
    50.4km=50400m
    then lets convert given hr into sec
    50400/60=840
    840/60=14m/s

  13. Given 14 meeter /sec
    So per minute=840 meeter
    per hour=50400 meeter
    1 km=1000meeter
    So ans is 50.4km/hr

    convert 14 meters in to KM —- 14/1000=0.014 Km
    Convert seconds into hrs —– 1*60*60 = 3600

    0.014 km per —— 1 sec
    ? ——- 3600

    cross multiple 3600*0.014/1= 50.4 Km/hr

  15. 1Hr = 3600s
    14*3600= 50400m/hr
    50.4 *10^3m/hr = 50.4 km/hr

  16. given speed = 14m/s
    so,,,,for 1min=14*60=840m
    then..for 1hr= 840*60=50400m
    we all know 1000m=1km
    so…50400m = 50.4km/hr

  17. 14 *60m. = 60 sec
    840 m.= 60 sec
    840*60m = 60*60 sec
    50400 m = 36000 sec
    50400m = 1 hr.
    50400/1000
    ans= 50.4 km/hr

  18. Just multiply the value by 3.6

    14m/s * 3.6 = 50.4 km/hr

  19. 14 m/s
    1hr=3600 sec
    so multiply by 3600 and dvide by same
    14*3600/3600 m/s
    50400/3600 m/s
    3600 s = 1hr
    1000m=1km
    50400=50.4km
    so
    50.4km/hr

  20. 1m/s=3.6km/h
    Therefore 14m/s=14*3.6=50.4km/h

  21. option B
    DISTAMCE COVER IN ONE HOUES=14*60*60=

  22. 3,600 seconds = 1 minute
    1Km = 1000m
    Therefore 3,600/1000 = 3.6 m/s
    Final answer = 14 metres * 3.6 = 50.4km/hr

  23. Basically to get all you need to do is
    14×3.6= 50.4

  24. convert 14 meters in to KM —- 14/1000=0.014 Km
    Convert seconds into hrs —– 1*60*60 = 3600

    0.014 km per —— 1 sec
    ? ——- 3600

    cross multiple 3600*0.014/1= 50.4 Km/hr

  25. the substitution is as follows
    14*(18/5)=50.4 is the correct answer

  26. Therefore, 1km = 1000 meters
    ⇒1 meter = 1 km1000
    Definition of Hour: A period of time equal to 60 minutes that is 3600 seconds.
    Definition of second: It is measured as the smallest unit of time.
    ⇒1 second =1 hr3600
    Now, 14meters per second need to be converted to kilometers per hour.
    Let x be 14 meters per second which is needed to convert into kilometers per hour
    ⇒x = 14ms
    ⇒141 km10001 hr3600
    ⇒14×36001000kmhr=50.4kmhr
    Therefore, 14 meters per second is equal to 50.4 kilometers per hour

  27. b) 50.4km/hr
    1km=1000m
    50.4km=50400m
    then lets convert given hr into sec
    50400/60=840
    840/60=14m/s
