A bus travels 54 km in 90 minutes. The speed of the bus is (a) 0.6 m/s (b) 10 m/s (c) 5.4 m/s (d) 3.6 m/s

Answer: (b) 10 m/s

Given parameters

Distance = 54 km

Distance = 54 × 1000 m

Distance = 54000m

Time = 90 minitutes

Time = 90 × 60

Time = 5400s

Therefore,

  • Distance = 54000m
  • Time = 5400s

Speed = Distance / Time

Speed = 54000/5400

Speed = 10 m/s
