The body moves for 15 minutes, the distance traveled is 4.5 km / h. Find the speed meter per second; kilometer per hour the body moves 10 m / s the distance traveled is 6 kilometers. Take some time.
To solve the problem, we need to perform the following actions (find the speed):
1.15 min * 4 = 1 hour;
2.4.5 km / h * 4 = 18 km / h = 5.000004 m / s.
Now we need to find T:
T = 6000m / 10m / s;
T = 600 s.
Answer: The time is 600 seconds; the speed is 5.000004 m / s.
