How does 50km/hr = 13.9m/s?
-------------------------------------------------------
answers:
Como say: 50000 / 3600 = 500 / 36 = 125 / 9 = 13 • 8888 .......= 13 • 9 m/s
-
sepia say: 50 km / hr
= 50000 m / 3600 s = 125 m / 9 s = 13.8888889 m/s = 13.9 m/s
-
Krishnamurthy say: 1 km = 1000 m and 1 hour = 3600 seconds
∴ 50 km / hr
= 50000 / 3600 = 125 / 9 = 13.8888889 = 13.9 m/s
-
lenpol7 say: 50 km = 50,000 m
1 hour = 3600 s(seconds)
Hence
50,000 / 3600 = 500 / 36 =250 /18 = 125 / 9 = 13 8/9 m/s = 113.8888.... m/s = 13.9 m/s
-
khalil say: 13.9 m in a second
13.9 x 3600 = 50040 m in an hour
1 km = 1000 m
so
50040 / 1000 = 50.040 km in an hour
-
TomV say: 50 km/hr = 50000 m/hr since each kilometer equals 1000 meters
50000 m/hr = 50000/3600 m/s since each hour contains 3600 seconds
50000/3600 = 13.888... which rounds to 13.9
Hence 50 km/hr = 50000/3600 m/s ≈ 13.9 m/s
-
oldschool say: This a dimensional analysis exercise:
50km/hr * 1000m/km *1hr/60min * 1min/60s = 50*1000/(60*60) = 125/9
125/9 = 13.889 or about 13.9m/s
-
no sea nabo say: 50㎞/h≈13.89㎧
50❌(1000m➗3600s)=13.88888
-
Brainard say: 50 km = 50 x 1000 m
= 50,000 m
1 hour = 60 mins x 60 secs
= 3600 s
50 km/h = 50, 000/3600 * m/s
= 125/9 m/s
= 13 8/9 m/s
= 13.8888888888888888888888 m/s
= 13.9 m/s ( 1 dp )
