Appx. 37.5 mph.
The average speed of that particular vehicle is precisely 65 kilometers per hour.
150/2.5 = 60 km per hour
It depends on how fast you are traveling. If you are traveling at 100 kph, or about 62 mph, you would cover the distance in 3.5 hours.
This time can be computed by dividing 64 by the average kilometer per hour your vehicle is traveling.
That depends a lot on the situation: the condition of the road, of the car, and the preferences of the driver. It can be anything between about 10 and 100 kilometers per hour.
As the rocks collide together they get smaller, so then the smaller ones are deposited further downstream, this is known as attrition.
Depends on how fast you are traveling. At an average speed of 95.56 kph (60 mph) it will take 7 1/2 hours to travel 450 kilometers.
Mars' average distance from the sun during the course of a complete orbital revolution is 141.6 million miles. That's about 52% farther than the earth's average distance from the sun.
More information is needed to find the rate.
Average speed is the distance traveled over a given time. For your case this would be: 210 km / 3 h Reducing this it becomes: 70 km/h (kilometers per hour)
your average speed is 50 kilometers per
