The definition of velocity, or at least speed, is distance/(time at speed), in this instance 10/9 km/min. (In advanced mathematics, "velocity" is a vector quantity, with both a magnitude and a direction. In that instance, a direction would also be needed but was not stated in the problem.)
The velocity of the train can be calculated by dividing the distance traveled by the time taken. In this case, the train travels 100 miles north in 2 hours, so the velocity is 100 miles / 2 hours = 50 miles per hour. Therefore, the train's velocity is 50 miles per hour to the north.
The velocity of the object is 10 m/s.
The minimum velocity of the missile would depend on the time it takes for the missile to reach the target. If the missile travels 100 meters in 1 second, then the minimum velocity would be 100 m/s.
500 meters/5 minutes = 100 meters per minute.
Yes. Velocity is a vector and therefore requires magnitude and direction: Magnitude: 100 kph Direction: North
The resultant velocity of a plane is 75 km/hr.
The resultant velocity of a plane is 125 km/hr.
The closing velocity is speed1 plus speed2, so the trains are moving toward each other at 250 mph. 2000/250 = 8. The trains will meet in 8 hours.
Velocity = Distance ÷ Time, therefore : Time = Distance ÷ Velocity. Time for journey = 877 ÷ 100 = 8.77 hours = 8 hours 46 minutes 12 seconds.
Yes, the International Space Station ISS travels round the world in just 92.89 minutes.
Think of average velocity as "overall" velocity. For example, if I walk down the block (let's say it's a distance of 100 meters), and it takes me 5 minutes, my AVERAGE velocity is just:v_ave = Δx/Δtwhere Δx is the change in position and Δt is the elapsed time.v_ave = (100 m) / (5 min)v_ave = (100 m) / (300 sec)v_ave = (1/3) m/sBut instantaneous velocity is a different concept: let's say for a while I walked, then I jogged, then I stopped, then I sprinted, then I walked. The overall trip still ended up taking me 5 minutes, so my average velocity is just as I've calculated it above, but my INSTANTANEOUS velocity changes as I change speeds at any given time in between.Hope this helps!
An example problem involving speed is calculating the average speed of a car that travels 100 miles in 2 hours. An example problem involving velocity is determining the velocity of a ball thrown upward with an initial velocity of 20 m/s at a height of 40 meters above the ground.
