For this case we have reef coral grows 0.13 meters per week, if we want to indicate how much will have grown in 15 weeks we have the following rule three:
0.13 metrs ---------------> 1 week
x -------------------------------> 15 weeks
Where "x" is the number of meters reef coral grows in 15 weeks.
[tex]x = \frac {15 * 0.13} {1}\\x = 1.95 \ m[/tex]
Thus, in 15 weeks it grows 1.95 meters.
Answer:
[tex]1.95 \ m[/tex]
