To convert 12 meters per second (ms) to kilometers per minute (km/min), we need to apply two conversion factors: one to convert meters to kilometers and another to convert seconds to minutes.
First, let’s break down the conversions:
- 1 kilometer = 1000 meters
- 1 minute = 60 seconds
Now, we can set up the conversion:
1. Convert meters to kilometers:
Since there are 1000 meters in a kilometer, we can multiply by the conversion factor of km/1000 m:
12 ms x (1 km / 1000 m)
2. Convert seconds to minutes:
Since there are 60 seconds in a minute, we can multiply by the conversion factor of 60 s/min:
12 ms x (60 s / 1 min)
Combining these two conversion factors into one equation gives us:
12 ms x (1 km / 1000 m) x (60 s / 1 min) = (12 x 60) / 1000 km/min
Doing the math:
(12 x 60) = 720
So, dividing by 1000, we get:
720 / 1000 = 0.72 km/min
Therefore, 12 meters per second is equal to 0.72 kilometers per minute.
