During their last workout, susan ran 3 1/2 miles in 30 minutes and her friend amber ran 2 1/3 miles in 20 minutes. each girl though she was the faster runner. based on their last run, whaich girl is correct?

3 1/2 miles in 30 minutes means that Susan can run 7 miles per hour

2 1/3 miles in 20 minutes means that Amber can run 7 miles per hour.

The answer would be b

Sin(a)+cos(a)+cot(a)-1=2(csc(x)+1)
