Answer 2

Task Solution

To solve the given problem, we can calculate the portion of the product scanned in the third hour using the information provided.

Let's denote the total product as P. According to the given information: - In the first hour, 2/5 * P is scanned. - In the second hour, 1/3 * P is scanned.

To find the portion of the product scanned in the third hour, we need to calculate the remaining portion after the first and second hours and then determine the portion scanned in the third hour.

Calculation

The portion of the product remaining after the first hour = P - (2/5 * P) = (3/5) * P The portion of the product remaining after the second hour = (3/5) * P - (1/3 * P) = (9/15 - 5/15) * P = (4/15) * P

Therefore, the portion of the product scanned in the third hour is 4/15.

Conclusion

After scanning 2/5 of the product in the first hour and 1/3 of the product in the second hour, the remaining portion of the product is 4/15, which is the portion scanned in the third hour.
