Average speed = Total Distance/Total Time = (15+25)/2 = 40/2 = 20 miles per hour.
Velocity (due North) = Total NET distance North/Total Time = (15-25)/2 = -10/2
= -5 miles per hour
or, velocity due South = 5 miles per hour.
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.
average velocity = miles/hours = (100 + 30)/(2 + 1) = 130/3 ≈ 43.33 miles/hour
50km/hour North.
Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.
A velocity vector includes both speed and direction.
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.
Speed = Distance divided by Time. So, speed = 75 miles divided by 2.5 hours = 75 / 2.5 = 30 miles per hour. Velocity is speed and direction, so the velocity is 30 mph Northbound.
The car's net displacement is 0 miles (north 50 miles - south 50 miles). Since the total time taken is 5 hours, the velocity is 0 mph because velocity is displacement divided by time, resulting in 0 mph.
average velocity = miles/hours = (100 + 30)/(2 + 1) = 130/3 ≈ 43.33 miles/hour
The velocity of the car is 65 miles per hour. This is calculated by dividing the distance traveled (260 miles) by the time taken (4 hours). Since direction is not specified in the calculation of velocity, the northeast direction does not affect the final answer.
30 miles per hour north
The average velocity during that period of time is 100 kilometers per 2 hours north. It may also be stated as 50 kilometers per hour north.
We're not completely sure what you mean by "per hour per second". Going just by what we see in the question, it's an acceleration, not a velocity. "Six miles per hour north" would be a velocity.
50km/hour North.
Velocity is speed and its direction. "30 miles per hour" is a speed. "30 miles per hour north" is a velocity". "30 miles per hour north" and "30 miles per hour south" are identical speeds but different velocities.
Velocity is speed plus direction. If you say you are traveling at 54 miles per hour, you are giving your speed. If you say you are going north at 54 miles per hour, you are giving your velocity.
The velocity of the winds blowing at 89 miles per hour during a storm on the North Carolina coast is 89 miles per hour.
