How do you calculate the average speed of a whole journey?
To calculate the average speed of an object, you must know the total distance an object travels and the total elapsed time of its whole journey….How To Calculate Average Speed
- To get average speed, s , divide total distance by elapsed time: Dt.
- To get elapsed time, t , divide total distance by speed: Ds.
What is the formula in finding the average speed and rate?
Average Speed = (Total distance)/(Total Time) = (1800 + 1800)/(30 + 45) = 3600/75 = 48 km/hr.
How do you find the average speed in meters per second?
Average speed can be calculated using the formula v=d/t where the variables are:
- v is the average speed of the object with units of m/s.
- d is the total distance or length of the path of the object with units of m.
- t is the total time taken to cover the path with units of s.
- Speed cannot have a negative value.
What is the average speed of the car on its complete trip?
50\% ~ Distance is 150 km, Speed is 30 km/h, Time is 5 hours. 50\% ~ Distance is 150 km, Speed is 50 km/h, Time is 3 hours. Combined Distance is 300 km, Combined Times is 8 hours. Answer: The Average Speed of the Car on its complete trip is 37.5 km/h.
Why is the average speed of 40mph more difficult to calculate?
The difficulty is that since the trip at 40mph takes longer, you spend more time going 40mph than you do going 60mph, so the average speed is weighted more heavily towards 40 mph. When calculating average speeds for fixed distances, it is better think of everything in minutes per mile rather than miles per hour.
How do you calculate average speed in miles per hour?
When calculating average speeds for fixed distances, it is better think of everything in minutes per mile rather than miles per hour. 60 miles per hour is 1 minute per mile, while 40 miles per hour is 1.5 minutes per mile. Since we travel the same number of miles at each speed, we can now take the mean of these two figures.
