Simply remember this triangle
D
-----------
S x T
The D represents Distance
The S represents Speed
The T represents Time
Distance divided by Time = Speed. (120 miles divided by 2 hours = 60 mph)
Distance divided by Speed = Time. (120 miles divided by 60 mph = 2 hours)
Speed multiplied by Time = Distance. (60 mph x 2 hours = 120 miles)
Distance = time * average speed (velocity) Average speed = Distance/time
Nearly! Speed is distance divided by time...
Average speed during the time = (distance) divided by (time for that distance)
Speed equals distance divided by time. By rearranging that formula, we get time equals distance divided by speed.
Speed = Distance divided by Time (S = D/T)Time = Distance divided by Speed (T = D/S)Distance = Speed times Time (D = S x T)
time
distance / time
Average speed is calculated by dividing the total distance covered divided by the time taken. Instantaneous speed is calculated as the derivative of displacement with respect to time.
time=distancedividedby speedbecause speed= distance divided by time and distance= speed*time
you calculate average speed by dividing the total distance to the total time.
Distance = rate*time. Thusly we can calculatae the speed an object is traveling if we know how far and in what length of time the object has traveled.
Speed gives the information that how fast a certain object is moving and it can be calculated by dividing distance with time in which that distance is covered
If only total distance and total time are considered, the speed calculated (total distance / total time) is the average speed of the entire trip.
It is the inverse of that: you divide distance by time to find speed (rate of movement). Some common units are meters per sec (m/sec) and miles per hour (mph).
Instantaneous speed is the speed at a specific instant. It is calculated as the average speed (defined as distance / time), for very small times.
