CONVERT 1 .5 m/s INTO km/h
Answers
Answer:
5.4 km/hr
Step-by-step explanation:
The easiest way to remember how to convert units is to iteratively multiply by 1 until you get what you want. You just have to pick the right forms of “1”.
“Meters per second” is m/s. You want km/h. To lose the m and gain a km, the form of “1” you want is (1 km)/(1000 m). Those distances are equal, so dividing one by the other is definitely 1, so is legal, and since it has m in the denominator, it will cancel the original m in the numerator of m/s.
1 m/s * (km/1000m) = 0.001 km/s
Next you see that you have s (seconds) but you want hours. We could do it all at once, but let’s do it in steps.
0.001 km/s * 60 s/m * 60 m/h = 3.6 km/h
This is legal because 60 s is a minute, and 60 m is an hour, thus each of those terms is “1”. And you are done because the units are what you wanted!
Hopefully it will help you !!
