10.9 m/s
3.61 meters
100 meters per 15.00 seconds = 14.91 mph
100 meters / 11 seconds = 20.336 mph (rounded)
If an object is travelling 100 meters in 1400 seconds, then it is travelling (100 / 1400) or about 0.0714 meters per second.
100 meters/14.00 seconds (1 mile/1609 meters)(3600 seconds/1 hour) = 15.982 miles per hour
To calculate speed, divide the distance traveled by the time taken. In this case, traveling 100 meters in 30 seconds means you would be going at a speed of 3.33 meters per second.
Half a second every metre.
3.61 meters
The velocity of the object is 10 m/s.
(100,000 meters/hour) x (0.13 second) / (3,600 seconds / hour) = 3.6111 meters (rounded, repeating)
6.66 meters per second.
100 meters per 15.00 seconds = 14.91 mph
100 meters / 11 seconds = 20.336 mph (rounded)
Just divide the distance by the time. This will give you the speed in meters/second. If you want to convert that to kilometers/hour instead, multiply the result by 3.6.
The average velocity is zero as the car returns to its starting point, having no displacement. The average speed, however, is the total distance traveled divided by the total time, which is 2π*200 meters divided by 62.8 seconds.
If an object is travelling 100 meters in 1400 seconds, then it is travelling (100 / 1400) or about 0.0714 meters per second.
11.99 seconds because 100 yard dash is 91 meters. 100 meters/91 meters = 1.09 Then do 11 seconds x 1.09 = 11.99 seconds. If you round it, you basically be getting a 12 second 100 meter dash.
