Question

When cars are coupled, they should be brought together from a few feet apart at a speed of about one mile per hour. This speed is MOST nearly equal to ________.

Answer 1

One mile per hour is approximately equal to 0.44704 meters per second, which can be rounded to 0.45 m/s for simplicity.

Step-by-step explanation:

To convert the speed of one mile per hour to a different unit of measure, we can use the conversion factor that 1 mile is equivalent to 1.60934 kilometers, and there are 3600 seconds in one hour. Therefore, one mile per hour (mph) can be converted to meters per second (m/s) through the following calculation:

• 1 mile per hour = 1 mile / 1 hour
• Convert miles to kilometers: 1 mile = 1.60934 kilometers, so 1 mph = 1.60934 km/h
• Convert kilometers per hour to meters per second: 1 km/h ≈ 0.277778 m/s, so 1.60934 km/h ≈ 1.60934 * 0.277778 m/s ≈ 0.44704 m/s

This means that a speed of one mile per hour is approximately equal to 0.44704 meters per second. We round this to two decimal places for convenience, getting 0.45 m/s.
