Velocity (or speed) = Distance ÷ Time
In this example, speed = 120/2 = 60 kph
40 mph
120 miles 60 mile per hour * 2 hours 60 * 2 = 120
It is a measurment of speed, and means that if the speed remains constant the object will travel 120 kilometers in one hour.
To find the average speed you must know the total distance traveled and the total elapsed. The distance traveled in each interval is simply the speed multiplied by the time (v x t). Thus, in the first interval you travel 120 x 1 = 120 meters, in the second interval 120 x 6 = 720 meters; therefore, the total distance traveled is 840 meters. The total time elapsed is 120 + 120 = 240 seconds. An average speed is simply the total distance traveled divided by the total time elapsed thus in this case it is 720 m / 240 s = 3 m/s.
speed = distance over time speed = 120/2 = 60 km/hr
40 mph
180 mph
420
120 miles 60 mile per hour * 2 hours 60 * 2 = 120

speed = distance over time speed = 120/2 = 60 km/hr
At 80 km/hr - which I am assuming is what you meant by 80 km, a car will travel 120 km. To make that journey in 2 hours, it must travel at 120 km/2 hr or 60 km/hr.
To find the average speed, divide the distance travelled by the time. By this procedure, the average speed is 60 km/h.
It is: 120/5 = 24 mph
Time = Distance/Speed = 120/115 = 1.04 hours, approx.Time = Distance/Speed = 120/115 = 1.04 hours, approx.Time = Distance/Speed = 120/115 = 1.04 hours, approx.Time = Distance/Speed = 120/115 = 1.04 hours, approx.
If you drive at 167km/hr then you will be at your destination in 1 hour. If you drive at 80km/hr then it 167 / 80 = 2.0875 hours. Note that the speed above must be your average. So if you go a constant 80 in the city and 160 on the highway your average is 120. At that speed you will be there in 167 / 120 = 1.39 hours.
