How do you convert 50 kilometers per hour to miles per hour?

Answer 1

1. Point your web browser to Google.com
2. type into the search field (without quotation marks) "50 km/h in mph"
3. Press
4. Read the conversion in bold text
5. Round off ot an appropriate number of significant figures

In this case google gives you:

31.0685596_mphRound off to 30 (or 31 mph in case the 0 of 50 was significant)

Another contributor says:

The first answer, above, will certainly do the trick. But I'm very bothered by any answer

that says "You solve this arithmetic problem by keying the numbers into the machine and

reading what comes out."

If the questioner adopts this technique, then

A). S/he'll never learn anything.

B). S/he won't recognize the garbage that comes out of the machine when s/he makes

a mistake keying the problem into it.

C). S/he'll be at a complete and total loss if s/he needs an answer and doesn't happen to

have a computer and internet access available at the moment.

Please accept the following slightly more useful answer, in lieu of going through the

complete derivation:

In order to convert kilometers to miles, or kilometers per hour to miles per hour ...

Divide by 1.6093

Algebraic Steps / Dimensional Analysis Formula 50 km/hr*1000 m/hr

1 km/hr*3.2808 ft/hr

1 m/hr*1 mi/hr

5280 ft/hr=31.06855961 mi/hr

Direct Conversion Formula 50 km/hr*1 mi/hr

1.609344 km/hr=31.06855961 mi/hr
