Question

Shane requires exactly 50 seconds to run 2 rounds around his school field.

Assuming he maintains a constant speed throughout, what is his.
a. Period
b. Frequency

Answer 1

`\\ \bull\tt\leadsto Period=(Time\:taken)/(No\:of\:rounds)`

`\\ \bull\tt\leadsto Period=(50)/(2)`

`\\ \bull\tt\leadsto Period=25s`

Now

`\\ \bull\tt\leadsto Frequency=(1)/(Period)`

`\\ \bull\tt\leadsto Frequency=(1)/(25)`

`\\ \bull\tt\leadsto Frequency=0.04s^(-1)`

`\\ \bull\tt\leadsto Frequency=0.04Hz`
