Question

1. You have two pieces of tape of 56 metres and 56 metres in length. If you connect both pieces together end-to-end hew long is your new piece of tape?

​

Answer 1

If the two pieces of tape are truly placed end-to-end, there will be no tape at the joint to connect the two pieces. In the real world, one of the 56 m pieces will have to overlap one end of the other piece to make up a single new piece of tape whose length must be a little less than 2(56 m), or a lilttle less than 112 m. There is no one specific correct answer because the experimenters vary in how much tape overlap to allow.
