Want this question answered?
velocity = distance / time time = distance / velocity time = 343 miles / 70 miles per hour = 4.9 hours
Safe distance is 2 seconds, or 4 car lengths. More if snow is on the ground or its raining.
Velocity basically just means speed. We drove at a high velocity down the highway.
If the velocity of the object is constant, then the net force on it is zero.(Incidentally, if the velocity of the car is constant and not zero, then it must be ona straight highway. If the highway curved and the car's velocity didn't change, thenit would run off of the road.)
Distance = Rate X Time so.... Rate = Distance/Time 210 miles/30 hours = 7 miles per hour
144/48 = 3 hours
Typically I get 17-19 mpg in the city, and 22 mpg on the highway. With long distance driving I have been able to average 26 mpg on the highway.
Velocity: average of 80 km per hour due North, 0 when at station. Distance: 80 km. Speed : average of 80 km per hour, 0 when at station. Displacement: 80 km.
$500,000,000 for the average highway. $500,000,000 for the average highway.
The average distance from the Earth to the Sun is 149,597,890 km. Therefore in one year the Earth travels a distance of 2*Pi*(149,597,890)km. This means that the velocity is about: velocity=2*Pi*(149,597,890)km/1 year and if we convert that to more meaningful units (knowing there is 365 days in a year, and 24 hours per day) we get: velocity=107,300 km/h (or if you prefer 67,062 miles per hour) So the Earth moves at about 100,000 km/h around the Sun (which is 1000 times faster than the speeds we go at on a highway!)
The highway distance is about 800 miles from Richmond to Chicago.
Taking a turn on the highway.
