To find the speed, we will use the formula: Speed = Distance / Time

Given:

• Distance = 1440 km
• Time = 2 hours

First, calculate the speed in km/h:

Speed = 1440 km / 2 hours = 720 km/h

Now, convert the speed from km/h to m/s:

1 km = 1000 meters

1 hour = 3600 seconds

Therefore, to convert km/h to m/s, multiply by 1000/3600 (which simplifies to 5/18):

Speed in m/s = 720 km/h * (5/18)

Speed in m/s = 720 * (5/18) = 200 m/s

Therefore, the person's speed is 720 km/h or 200 m/s.
