1.5 meters.
If the child slows down 3 meters per second every second for 4 seconds, he'll have slowed down 12 meters per second total. Having started at 15, he'll be down to a speed of 3 meters per second.
5 meters
Just divide the distance by the time. The answer, of course, is in meters/second (meters per second). If you want to convert this to kilometers per hour, multiply the number of meters/second by 3.6.

That's easy, if the car is initially traveling at 25 meters per second and gradually accelerates 3 meters per second for 6 seconds then the car is traveling at 43 meters per second.
If an object is travelling 100 meters in 1400 seconds, then it is travelling (100 / 1400) or about 0.0714 meters per second.
10.2888888 is the speed in meters per second of a ship traveling at 20 knots.
At 10 miles per hour, a car is traveling 16,090 meters per hour.
The magnitude of the balls displacement is 9 meters.
At 40 centimeters per second, you are traveling 24 meters per minute.
