It describes how quickly or slowly an object moves from one place to another. The standard (SI) unit of speed is meters per second (m/s), but it can also be expressed in other units, such as kilometers per hour (km/h), miles per hour (mph), or feet per second (ft/s), depending on the context or the country's measurement system.

You can express acceleration by standard acceleration due to gravity near the surface of the Earth, which is defined as g = 31.17405 ft/s² = 9.80665 m/s². For example, if you say that an elevator is moving upwards with the acceleration of 0.2g, it means that it accelerates with about 6.2 ft/s² or 2 m/s² (i.e., 0.2 × g). We rounded the ...
Kilometers per hour to Meters per second Conversion Example. Task: Convert 75 kilometers per hour to meters per second (show work) Formula: km/h ÷ 3.6 = m/s. Calculations: 75 km/h ÷ 3.6 = 20.8333333333 m/s. Result: 75 km/h is equal to 20.8333333333 m/s.
Convert a journey distance in kilometres and the time taken in hours, to an average speed in mph. Determine the average speed of a runner in mph, from a track run distance in metres, and the stopwatch time in minutes or seconds. Calculate a training speed to complete a cycling route within a target period of time.
The first plane is flying 25 km/h slower than the second plane. In two hours, the planes are 430 kilometres apart. Find the rate of each plane. On a 130-kilometre trip, a car travelled at an average speed of 55 km/h and then reduced its speed to 40 km/h for the remainder of the trip. The trip took a total of 2.5 hours.
