Iím riding my push bike at 25 km/h and my tyre radius is 30.5 cm.
How many revolutions per min are my wheels travelling at?
Can someone please help with this tricky question, sorry if this is in the wrong category(im new to this forum and wasn't sure which one to put the question in)
Another remark is that to get a final answer with 2 dp, it is not sufficient to round all intermediate results (the number of meters traveled in a minute and the circumference) to 2 dp. You should do all calculations with maximum precision and remove all but 2 dp only from the final answer. It is possible to have less than maximum precision for intermediate results, but to know which precision is sufficient requires a finer analysis.
