∙ 15y agoTo 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.

∙ 15y agoThe average speed is 120 miles per hour.
Velocity (or speed) = Distance ÷ Time In this example, speed = 120/2 = 60 kph
speed = distance over time speed = 120/2 = 60 km/hr
It is: 120/5 = 24 mph
10 metres in 5 seconds is a speed of 2 metres/second, or 120 metres/minute = 7200 metres/hour or 7.2 kilometres/hour.
The average speed is 120 miles per hour.
You haven't mentioned distances or speed or acceleration, so this cannot be answered.
To find the average speed, we need to know the time it took for Carlos to reach his friend's home. If he walked the 100 m in 2 minutes (120 seconds), his average speed would be 100 m / 120 s = 0.83 m/s.
450 km = 450000 metres Time = Distance/Speed = 450000/120 seconds = 3750 seconds.
speed = distance over time speed = 120/2 = 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.
120 seconds = 2 minutes 120 seconds = 0.03 hour
It is: 120/5 = 24 mph

10 metres in 5 seconds is a speed of 2 metres/second, or 120 metres/minute = 7200 metres/hour or 7.2 kilometres/hour.
1 minute = 60 seconds → 120 minutes = 120 × 60 seconds = 7200 seconds
