<h2>
Therefore she must swim =6.5 miles the seventh week</h2>
Step-by-step explanation:
Given , Rebecca plans to swim an average of 5.5 miles per week.
So, she has swum 2 miles the first week ,7 miles the second week ,6 miles the third week ,9 miles the fourth week ,5 miles the fifth week and 3 miles the sixth week.
Total she has swum =(2+7+6+9+5+3) miles in six week.
=32 miles
To reach her goal she has to swim =(5.5×7)miles= 38.5 miles at the end of seventh week.
Therefore she must swim =(38.5 - 32) miles =6.5 miles the seventh week
