Answer:

16.6 km/h  

Step-by-step explanation:

Speed = distance/time

           = 400.0 m/86.8 s

           = 4.608 m/s               Convert kilometres to metres

Speed = 4.608m/s × (1 km/1000 m)

           = 0.004 608 km/s     Convert seconds to hours

Speed = 0.004 608 km/s × (3600 s/1 h)

           = 16.6 km/h
