If Mrs. Hayakawa walks to and from work instead of taking the bus for 5 weeks, she will save the bus fare of $2.40 per trip.
The number of workdays in 5 weeks is (5 days/week) * 5 weeks = 25 days.
For each workday, she would have spent $2.40.
Therefore, the total benefit she would get by walking to and from work instead of taking the bus for 5 weeks is 25 days * $2.40/day = $<<25*2.40=60>>60. Answer: \boxed{60}.
