What is the average speed of a car that takes 3 hours to travel 120 miles?
40 mph
A car traveled at an average speed of 60 mph for two hours How far did it travel?
120 miles 60 mile per hour * 2 hours 60 * 2 = 120
What is 120 kilometers per hour?
It is a measurment of speed, and means that if the speed remains constant the object will travel 120 kilometers in one hour.
What is the average speed of a car that travels 120 kilometers in two hours?
speed = distance over time speed = 120/2 = 60 km/hr
What is the average speed if you walk for 120 seconds at 1ms then run for 120 seconds at 6ms?
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.
