The formula for average speed is expressed as follows. Average speed = Total distance ÷ Total Time. This Average Speed Equation is the basic formula that is applied everywhere.
The average speed of an object is the total distance the object travels divided by the total amount of time taken.
Thus we can find the average speed as: Average Speed = (Total distance)/(Total Time) = (1800 + 1800)/(30 + 45) = 3600/75 = 48 km/hr. Hence the correct option here is C) 48 km/hr. So to find the average speed never use the formula of the averages but try to find the total distance covered and the total time taken.
If the two different speeds of the given journey are given, calculate the two distances separately using the formula: distance = Speed × time. Step 2: Calculate the time taken to travel the total distance. Step 3: Divide the total distance by total time taken to find the average speed.
To find the average Speed with the only given factor as speed - without time and distance given - add the initial speed to the final speed in the entire journey and divide the answer by 2.
The formula for determining the average speed is S = d/t, where S stands for the average speed, d stands for the entire distance, and t stands for the complete amount of time. Ans : Average velocity is always smaller than average speed since displacement is less than the distance traversed.
The direct proportion formula says if the quantity y is in direct proportion to quantity x, then we can say y = kx, for a constant k. y = kx is also the general form of the direct proportion equation.
The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.
Average This is the arithmetic mean, and is calculated by adding a group of numbers and then dividing by the count of those numbers. For example, the average of 2, 3, 3, 5, 7, and 10 is 30 divided by 6, which is 5.
Average speed is a rate that is a quantity divided by the time taken to get that quantity. SI unit of speed is meters per second. Average speed is calculated by the formula S = d/t, where S equals the average speed, d equals total distance and t equals total time.
