Explanation:

Step1: Convert kilometers to meters

1 km = 1000 m, so 80 km = 80×1000 m.

Step2: Convert hours to seconds

1 hour = 3600 s.

Step3: Calculate the speed in m/s

Speed \(v=\frac{80\times1000}{3600}\text{ m/s}=\frac{80000}{3600}\text{ m/s}=\frac{200}{9}\text{ m/s}\approx 22.22\text{ m/s}\)

Answer:

\(\frac{200}{9}\text{ m/s}\approx 22.22\text{ m/s}\)
