100 meters per 15.00 seconds = 14.91 mph
100 meters / 11 seconds = 20.336 mph (rounded)
The initial velocity is 10 meters/sec and is thrown up against the gravitational pull of the earth. This means that the ball is experiencing a deceleration at the rate of 9.8 meters/sec/sec to bring its final velocity to zero. v^2 - u^2 = 2gs where u is the initial velocity, v the final velocity, g is the acceleration or deceleration, and s is the distance traveled. 0^2 - 10^2 = 2 x (-9.8) x s -100 = -19.6s 100 = 19.6s s = 100/19.6 = 5.102 meters Now v = u + gt where v is the final velocity, u is the initial velocty, g is the acceleration or deceleration, and t is the time. When the ball is thrown up with 10 meters/sec velocity it is acted upon by the deceleration of gravity until its velocity becomes zero. So 0 = 10 - 9.8t or 9.8t = 10 t = 1.020 seconds The time for the ball to go up is 1.020 seconds and the same time is taken for the ball to come back for a total of 2.040 seconds.
If an object is travelling 100 meters in 1400 seconds, then it is travelling (100 / 1400) or about 0.0714 meters per second.
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.

(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
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.
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.

That's 0.1 km per second for 8x3600 seconds, equals 2880 km
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.
