The average speed will be:
Total distance travelled divided by time taken
Total distance (in metres)= 80+125+45=250
Total time (minutes) =10
250/10
=25
Thus Mary's average speed is 25 metres per minute.

= 2
Explanation:
During nuclear fusion, two lighter nuclei of elements combine to form heavy nucleus and also energy is released;
During the process of hydrogen fusion a nucleus of deuterium is formed from two protons with emission of a neutrino.
In this case deuterium fuses with hydrogen nuclei to form helium-3 and also release energy.
That is;
2/1 H + 1/1 H = 3/1 He + energy
