Final answer:

Step-by-step explanation:
To find the total hours Darren spent on his homework, we need to add up the number of hours from Wednesday and Thursday.
On Wednesday, Darren spent 2 1/2 hours, which is the same as 2 hours and 30 minutes.
On Thursday, Darren spent 1 3/5 hours, which is the same as 1 hour and 36 minutes.
To add the hours and minutes, we can convert everything to minutes and then convert it back to hours and minutes.
2 hours and 30 minutes is equal to 2 * 60 + 30 = 150 minutes.
1 hour and 36 minutes is equal to 1 * 60 + 36 = 96 minutes.
Adding the minutes together, we get 150 + 96 = 246 minutes.
Converting it back to hours and minutes, we have 246 minutes, which is equal to 4 hours and 6 minutes.
So, Darren spent a total of 4 hours and 6 minutes on his homework.
