Provided that:
- Distance = 5 metre
- Time = 10 seconds
To calculate:
- The speed in m/s
- The speed in cm/s
Solution:
- The speed in m/s = 0.5 m/s
- The speed in cm/s = 50 cm/s
Using concepts:
- Speed formula
- Formula to convert m into cm
Using formulas:
- Speed = Distance/Time
- 1 m = 100 cm
Required solution:
★ Finding speed in metre per second!
→ Speed = Distance/Time
→ Speed = 5/10
→ Speed = 0.5 metre per second
★ Finding speed in cm per second!
~ Firstly let us convert m-cm!
→ 1 metre = 100 centimetres
→ 5 metre = 5 × 100 centimetres
→ 5 metre = 500 centimetres
~ Now let's calculate speed!
→ Speed = Distance/Time
→ Speed = 500/10
→ Speed = 50 cm per second!
