i got this one totally wrong too

But here is my teachers solution:

Period is pi
amp is 2

Therefore in pi secs it travels 8 metres ( 2 metres to end point, 2m back to origin then to other end point and back to origin)

Therefore in 1 sec it travels 8/pi metres

Therefore in 60 secs it travels 60 x 8/pi metres

= 153 metres in one minute

Hope that helps
