You have a distance and a time so you can work out the bikes speed which would be distance/time so 40mph.
Explanation:
The temperature must be hot enough to allow the ions of deuterium and tritium to have enough kinetic energy to overcome the Coulomb barrier and fuse together. The ions must be confined with a high ion density to achieve a suitable fusion reaction rate.
Option (C) is correct that the majority of the elements on the periodic table are metals.
