Question

Convert 55 kilometers per hour into meters per second. Use the conversion factor 1 km = 1000 m.

55 ______/ _____ ´ 1000 _____/1 ______ ´ 1 ______/60 ______
´ 1 _____/60 _____ = 15 _____

Answer 1

To convert 55 km/h to m/s, multiply by 1000 to change km to m and then divide by 3600 to change hours to seconds, resulting in approximately 15.28 m/s.

Step-by-step explanation:

To convert 55 kilometers per hour (km/h) to meters per second (m/s), you can use the conversion relationship that 1 km = 1000 meters (m) and 1 hour = 3600 seconds (s). The conversion requires two steps:

• Convert kilometers to meters.
• Convert hours to seconds.

The calculation is as follows:

1. Multiply 55 km/h by 1000 m/km to convert the distance from kilometers to meters. This results in 55000 meters per hour.
2. Divide 55000 meters per hour by 3600 s/h to convert time from hours to seconds. This yields approximately 15.28 meters per second.

Therefore, 55 kilometers per hour is approximately 15.28 meters per second.

Answer 2

55km/1hr x 1000m/1km x 1hr/60min x 1min/60sec =

(55 x 1000)/(60 x 60) =

55000/3600=

Answer: 15.28 m/sec
