She can increase her exercise for 5 week
Okay, lets take a look at this.

So we start of with the constant of 20 minutes.

She increases it 5min/week.

We can form an equation which is 45=5x+20.  We can easily solve this by subtracting 20 from both sides and dividing both sides by five, ending in 5 as the answer.

Answer: 5 weeks
