Question

Ted started working on his science project at 3:39 p.m. It took him 1 hour and 45 minutes to finish the project. Then, he worked on his math assignment for 43 minutes. When did Ted finish his math assignment?

Answer 1

Ted finished his math assignment at 6:07 p.m.

Step-by-step explanation:

To find when Ted finished his math assignment, we need to determine the time elapsed from when he started his science project until he finished it, and then add the duration of his math assignment.

Ted started his science project at 3:39 p.m. and it took him 1 hour and 45 minutes. To find the finishing time of his science project, we add 1 hour and 45 minutes to 3:39 p.m., which gives us 5:24 p.m.

Then, Ted worked on his math assignment for 43 minutes. To determine the finishing time of his math assignment, we add 43 minutes to 5:24 p.m., which gives us 6:07 p.m. Therefore, Ted finished his math assignment at 6:07 p.m.

Answer 2

Ted finished his math assignment 2 hours and 28 minutes after he started working on his science project.

Step-by-step explanation:

To find when Ted finished his math assignment, we need to add the time it took for him to finish his science project and the time he worked on his math assignment.

Ted finished his science project in 1 hour and 45 minutes, and then he worked on his math assignment for an additional 43 minutes.

To find the total time, we add 1 hour and 45 minutes to 43 minutes:

1 hour 45 minutes + 43 minutes

= 1 hour 88 minutes

Since there are 60 minutes in 1 hour, we can simplify 1 hour 88 minutes as:

1 hour 88 minutes = 1 hour + 60 minutes + 28 minutes

= 2 hours 28 minutes

Therefore, Ted finished his math assignment 2 hours and 28 minutes after he started working on his science project.
