For this question, we just need to know that 1h = 60 minutes. So let's illustrate our situation below:
As we can see above 45 min = 10 min + 10 min + 10 min + 10 min + 5 min. So all we need to do is to start to sum step by step over 4:32 pm as follows:
4:32 pm + 10 min = 4:42pm
4:42 pm + 10 min = 4:52pm
4:52 pm + 10 min = 5:02pm
5:02 pm + 10 min = 5:12pm
5:12 pm + 5 min = 5:17pm
As shown on the picture above. So our final answer is 5:17pm
