36 cm/sec to mph
The correct answer and explanation is:
Correct Answer:
36 cm/sec = 0.805 mph (approximately)
Explanation:
To convert 36 centimeters per second (cm/sec) to miles per hour (mph), you need to follow a series of unit conversions. Start by converting centimeters to meters, then meters to kilometers, and finally kilometers to miles. Also, convert seconds to hours to complete the unit transformation.
- Convert centimeters to meters
There are 100 centimeters in a meter:
36 cm/sec ÷ 100 = 0.36 m/sec - Convert meters per second to kilometers per hour
There are 1000 meters in a kilometer and 3600 seconds in an hour:
0.36 m/sec × (3600 sec/hour) ÷ 1000 = 1.296 km/h - Convert kilometers per hour to miles per hour
1 kilometer is approximately 0.621371 miles:
1.296 km/h × 0.621371 = 0.805 mph
Thus, 36 centimeters per second is approximately 0.805 miles per hour.
This conversion is important in understanding different speed measurements used in various systems. The metric system commonly uses centimeters per second and meters per second, while the imperial system, particularly in the United States, often expresses speed in miles per hour. Being able to convert between these systems is essential in physics, engineering, travel, and everyday use.
For example, if a small robotic vehicle moves at 36 cm/sec, its speed might seem fast or slow depending on the context. Converting to mph gives a better sense for those familiar with car speeds. In this case, 0.805 mph is a relatively slow pace, suitable for slow-moving machinery or walking robots. Understanding and converting units accurately allows clearer communication of measurements across different scientific and practical fields.
