a train is traveling at a speed of 68 mph.express its speed in meters per second.?

Question

how to convert miles per hour to meters per hour?

Answer 1

Here is your homework:

1mph=1.6093kph
68mph=68x1.6093=109.4324kph
109432.4 meters / 60min=1823.8733 meters per minute.
1823.8733 / 60 seconds= 30.3978 meter per second


or 1mph=1.4667 feet per sec.
68mph= (1.4667 x 68) =99.7356 feet per second
1meter=3.28084feet
99.7356 / 3.28084=30.3994Meters per second

The difference is rounding error.

Answer 2

Actually, if you go to google, and type in 68 miles per hour to meters per second, you'll get your answer.

68 miles per hour = 30.39872 meters per second

To do the actual math, 68mph x (1609.344 meters per hour/1 mile per hour) to get meters per hour, then x by (1 hour/60 minutes) then x by (1 minute/60 seconds). It's the same as 68x1609.344/60/60, so the answer is approximately 30 if you care about significant figures.

Answer 3

1600 meters in a mile.., multiply mph by 1600 to get m/hr
Since 1600m = 1 mile, you can divde 1600m by 1 mile to get 1.

1600m/1mi = 1

(68mi / 1hr) (1600m / 1mi)

The 1 mi cancels, and you're left with m/hr

Don't forget that the question asks for m/s, not m/hr.

Addendum: I advise against using google to do homework like this. You will not have internet access on an exam, and you need the basics if you're going to understand more advanced concepts later (for which people in general will not know the answers to).

Answer 4

1609 m in a mile.... So 68*1069=72692meters/h

3600 seconds in an hour

72692/3600=20.19m/s

Answer 5

and divide the result you get by 3600 (1 hour = 60 min = 3600 s)
you'll get arround 30.39 m/s

Answer 6

you should try 1st b4 coming on here for the answer so at least youll know how to get the answer if its on the test
