The speed of the car is precisely 20 meters per second, or 72 kilometers per hour.
My speed is zero, since I am sitting on my porch watching the car whiz by at 72 kilometers per hour.
To calculate the runner's average speed, you would use the formula: speed = distance ÷ time. In this case, the distance is 100 meters and the time is 15 seconds. Therefore, the average speed of the runner would be 100 meters ÷ 15 seconds = 6.67 meters per second.
To calculate average speed, you would use the formula: average speed = total distance / total time. In this case, the total distance is 100 meters and the total time is 55 seconds. Therefore, the average speed would be 100 meters / 55 seconds = 1.82 meters per second.
100 meters in 9.77 seconds equates to an average speed of 22.9 mph
6.25 meters per second
10 meters per second 100/10=10
9.09 m/s
To calculate the speed of the elk, you would use the formula: speed = distance/time. In this case, the distance covered is 100 meters and the time taken is 5 seconds. So, the speed of the elk would be 100 meters / 5 seconds = 20 meters per second. Therefore, the elk is running at a speed of 20 meters per second.
To calculate the runner's average speed, you would use the formula: speed = distance ÷ time. In this case, the distance is 100 meters and the time is 15 seconds. Therefore, the average speed of the runner would be 100 meters ÷ 15 seconds = 6.67 meters per second.

To calculate the speed of the car, you would use the formula speed = distance/time. In this case, the distance is 100 meters and the time is 50 seconds. Plugging these values into the formula, you get speed = 100 meters / 50 seconds = 2 meters per second. Therefore, the speed of the car is 2 meters per second.
10 meters per second 100/10=10
s=d/ts= 100 / 12s= 8.33ms-1
8.3 m/s
8.3 m/s
You are supposed to use the definition of "average speed", and simply divide distance by time. The answer will be in meters/second. If you want to convert that to kilometers/hour, multiply the result by 3.6.
