The mathematical expression to calculate the speed is s=dt. Here, s is the speed of an object in meters per second, d is the distance in meters, and t is the time in seconds. Answer and Explanation: Based on scientific conversion: 1milesperhour(mph)=1.60934kilometerperhour(kmph). {...
But I will point out that a similar question might ask what is the average speed, given that these three different speeds were applicable over three distinct legs of a trip. Then the total miles driven divided by the total time would give the average speed for that trip, which very lik...
First we have to understand the average speed of a particle to solve this problem: Average Speed: It is defined the total distance which is covered by the particle with respect to time. Suppose {eq}D {/eq} is the total distance which is covered by the particle and {eq}T {/eq...

The speed of light in MPH is 670,616,629 mph, 299,792,458 meters per second, or 186, 282 miles per second. Light takes approximately one second to travel the 238,854 miles to the moon. The speed of light is considered a physical constant that is used in many areas of physics. This...
What Is Speed? AGrigorjeva/iStock/GettyImages Anyone who drives a car is familiar with the concept of speed. It's the number on the speedometer that tells you how fast the car is going. In automobiles, speed is measured in miles per hour (mph) or kilometers per hour (kph), but ...
The car has a top speed of 147 mph An engine running at full speed Acceleration In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction). Speed Each of the possible ge...
Is a photon a particle? What is the speed of light in mph? What is the energy of a photon of blue light? What is the speed of light per minute? What if the speed of light was faster? How are the wavelength and energy of a photon related?
