class starts at 9:30 and finishes at 10:15. spend twice the time in math class, at 1:10, what time they finish math?
Class takes 45 minutes (1 1/2 hours.)
What is the twice 45 minutes?
What time does math class end?
To find out what time the math class finishes, let's break down the given information step by step:
1. The class starts at 9:30 and finishes at 10:15. This means that the duration of the class is 10:15 - 9:30 = 45 minutes.
2. The question states that the math class lasts twice as long as the given duration. Therefore, the duration of the math class is 2 * 45 minutes = 90 minutes.
3. The math class starts at 1:10. To figure out when it finishes, we need to add the duration of the class (90 minutes) to the starting time (1:10).
To add the duration to the starting time, we need to do the following:
- Convert the starting time to minutes: 1 hour = 60 minutes, so 1:10 can be converted to 70 minutes.
- Add the duration of the math class to the starting time in minutes: 70 + 90 = 160 minutes.
- Convert the total minutes back to hours and minutes: 160 minutes = 2 hours and 40 minutes.
Therefore, the math class finishes at 1:10 + 2 hours and 40 minutes = 3:50.
