For example, if you have speed in mph (miles per hour), time should also be in hours. The calculator is a completely free, no obligation, online advice service. average speed = total distance / total time The most common units of measurement for average speed are “kph” or kilometers per hour, “mph” or miles per hour, “m/s” or meters per second, and “ft/s” or feet per second. Let's calculate how the sound propagates in cold water - like really cold, from wintering swimming activities. The metric unit of the result will depend on the units you put in. The road conditions vary according to several factors including overall surface condition, depth of snow or ice, level of water on the road, etc. Wet-Ice-Smooth. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed. The speed of sound in the gas depends only on two constants - γ, R - and on the temperature but not on the air pressure or density as it is sometimes claimed. with a given distance and travel time. To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. For example, if you measured distance in meters and time in seconds, your output from the average speed calculator would be ft/s. The formula looks like this: average speed = total distance / total time Common units for speed are kilometers per hour (kph), miles per hour (mph), feet per second (ft/s), and meters per second (m/s). First, subtract the time spent at the train stops: 2.5 x 4 = 10 minutes. The time, or more precisely, the duration of the trip, can be calculated knowing the distance and the average speed using the formula: where d is the distance travelled, v is the speed (velocity) and t is the time, so you can read it as Time = Distance / Speed. To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. If you are outside that category, and do need any further help, then we are happy to assist.
