The average speed of a cloud as it moves across the sky is typically around 30 miles per hour.
The average speed of an object that moves 20m in 3 minutes is 20m/3 min = 6.67 m/min. For the second scenario, to calculate the average speed of an object that moves 20m in 30 min and 4 min, we sum the time first: 30 min + 4 min = 34 min. Then, the average speed is 20m/34 min ≈ 0.59 m/min.
Average speed and constant speed are alike in that they both involve measuring the rate at which an object moves over a certain distance. However, while constant speed refers to the speed that remains the same throughout the entire journey, average speed takes into account any changes in speed that may have occurred during the journey.
Yes, average velocity and average speed can be the same if an object moves in a straight line without changing direction. Average velocity takes into account both the speed of the object and its direction of motion, while average speed is the total distance traveled divided by the total time taken.
No, the average speed cannot be negative because speed is a scalar quantity that represents the rate at which an object moves in a particular direction. Negative speed would imply moving in the opposite direction, which is typically referred to as velocity.
No, the numerical ratio of average velocity to average speed is not always equal. Average velocity is a vector quantity that includes both magnitude and direction, while average speed is a scalar quantity that only considers magnitude. The ratio will be equal only when the object moves in a straight line.
When a line of clouds moves across the sky, it is an example of cloud motion due to wind patterns in the atmosphere. The movement of clouds is influenced by wind speed and direction in the specific atmospheric region where they are located.

The average forward speed of a hurricane is 10-15 mph
Yes, if the car moves in only one direction.
Jupiter moves faster than Mars. Jupiter's average orbital speed around the Sun is about 13.07 km/s, while Mars's average orbital speed is about 24.08 km/s.
The average speed of an object that moves 20m in 3 minutes is 20m/3 min = 6.67 m/min. For the second scenario, to calculate the average speed of an object that moves 20m in 30 min and 4 min, we sum the time first: 30 min + 4 min = 34 min. Then, the average speed is 20m/34 min ≈ 0.59 m/min.
There is no single answer. Electromagnetic energy moves at the speed of light, about 300,000 km/sec. Acoustic energy moves at the speed of sound in whatever medium you are using. Kinetic energy moves with the speed of the moving body. Thermal energy moves through a conducting body at various speeds, depending on how well the material conducts heat. So energy as a general term does not have a specific speed.
The average speed of boat in kilometers is per hour is 20 km /hr.
Velocity
Speed is distance/time. If you want to express the speed in km/h then convert time to hours: 45 min / (60 min/hour) = 0.75 hour. Then you have (15.0 km)/(0.75 h) = 20 km/h
The sun doesn't move across the Earth's surface; rather, the Earth rotates on its axis, causing the appearance of the sun's movement across the sky. The sun appears to move at an average speed of 15 degrees per hour due to the Earth's rotation.
