First 30k takes 45 min, second 30k takes 90 min, total 60k in 2¼ hours so average speed = 60 x 4/9 = 26 and 2/3 kph
His average speed is 55 kilometers per hour.
The average speed is 140 km/hr
a high speed train travels south for 2.00 h for a distance of 454km. what is its average velocity?

When an object travels in a straight line and at the same speed, we call it an uniform speed. When an object travels at different speeds, we say that the object is at non uniform speed.
At constant speed.
Uniform speed = Speed that doesn't change. Average speed = A number that represents the uniform speed that would have covered the observed distance in the observed time, although the actual speed at any moment during that time is unknown.
r=d/t is farmula of speed or uniform speed and its si unit is m/s.
40 MPH is the average speed
Its average orbital speed is 9.69km/s.
what is the average speed of a soccer ball that travels 34 m in 2 s
The average speed if an airplane travels 1364 miles in 5.5 hours is 248 miles/hr.
The average tornado travels at 35 mph.
The Average Speed means the total distance the object travels and the overall time it takes.
HEYAnswer:"Uniform" motion is motion with a constant speed in a straight line. Speed ordirection are not changing.If a body moving along straight line travels unequal distances in equal intervals of time, the body is said to be in Non uniform motion
For uniform acceleration the average speed is the initial speed plus the final speed divided by two.
