A Correct answer
Explanation

Speed = Distance / Time = 234 km / 1.6 hr = 146.25 km/hr. Convert to m/s: 146.25 * (5/18) = 40.625 m/s.

AI explanation

Convert the time to seconds by multiplying 1.6 by 3600 to get 5760 seconds, and convert the distance to meters by multiplying 234 by 1000 to get 234000 meters. Using the fundamental formula speed equals distance divided by time, the speed is 234000 divided by 5760, which equals 40.625. The required average speed is 40.625 m/s.
