30km/h = 30km/60min = 5km/10min 20km/h = 20km/60min = 10km/30min 5+10=15km

The average speed during that time is 20 km per hour. We can't say anything aboutthe velocity because you've told us nothing about the direction it traveled."Velocity" is NOT just a fancy word for 'speed'. It has a different meaning.

If you divide the distance by the time, you'll get the average speed. In this case, the answer will be in km/hour.
10 minutes 53 seconds at 65 mph / 105 kmh
20km/hr
It depends on the speed at which the train is traveling. At 100 km/h it will take approximately 20 minutes.
Distance = (speed) x (time)Time = (distance) / (speed)= 1 / 20 hour = 3 minutes
30km/h = 30km/60min = 5km/10min 20km/h = 20km/60min = 10km/30min 5+10=15km
Twenty minutes.

Speed equals the total of distance traveled divided by the total time of travel example: A bicycle total distance is 5km. The total of time is 1/4 of a hour 0.25 a hour. speed=5km/0.25h=20km per hour
