Question
A horse covers 500 m in 2 minutes. Its speed in SI units is ___.
- Always equal to
2.77 m/s
- 4.16 m/minute
- 2.77 m/minute
- 4.16 m/s
Hint:
Speed = Distance/Time
The correct answer is: 4.16 m/s
Speed = Distance/Time
Distance = 500m
Time = 2min = 60
2 sec. = 120 seconds
Speed = 
ms-1
Speed = 4.16 ms-1
The SI unit of distance is Meter(m) and SI unit of time is Seconds (s).
