## No problem! Let's go through the problem again step by step and find the correct solution.

Let's assume that the distance between Boston and Los Angeles is represented by 'd' miles.

We can set up two equations to represent the time it takes to fly from Boston to Los Angeles and from Los Angeles to Boston respectively:

1) Time taken from Boston to Los Angeles: t1

Distance = Rate * Time

d = 525 * t1

2) Time taken from Los Angeles to Boston: t2 (which is 40 minutes less than t1)

Distance = Rate * Time

d = 600 * t2

Now, we can solve these two equations to find the values of t1 and t2.

From equation 1), we can rewrite it as:

t1 = d / 525

Substituting this into equation 2), we have:

d = 600 * (d / 525 - 40/60)

Simplifying the equation:

d = 600 * (d / 525 - 2/3)

Now, let's solve for 'd' by multiplying both sides by 525:

525d = 600d - 400

Bringing 'd' terms to one side, we have:

600d - 525d = 400

75d = 400

Dividing both sides by 75:

d = 400 / 75

d â‰ˆ 5.33

Therefore, the distance between Boston and Los Angeles is approximately 5.33 miles.
