The table below compares the radioactive decay rates of two materials.

Material Original mass of material (in grams) Mass of material after 60 hours (in grams)
1 208 13
2 200 50
Based on the table, which of these conclusions is most likely correct? (2 points)
The half-life of Material 1 and Material 2 are equal.
The half-life of Material 2 is double the half-life of Material 1.
The half-life of Material 2 is 30 hours more than the half-life of Material 1.
The half-life of Material 1 is 30 hours more than the half-life of Material 2.
