What is the ration between the distance travelled by the oscillator in one time period and amplitude?

Explanation

The diagram repersents

the motion of a particle executing SHM between A and B.
Total distance travelled while it goes from A to B and returns to A is
`=AB+OB+BO+OA`
`A+A+A+A=4A` `[:'OA=A]`
Amplitude OA=A
Hence, ratio of distance and ampliude `=(4A)/(A)=4`
