Julian spent 45 minutes doing his math homework. He spent 35 minutes doing his science homework. Afterward, he did his reading homework. He ended up studying for 2 hours and 15 minutes altogether. How long did it take him to do his reading homework?
60*2 + 15 - 45 - 35 = ?
Leslie can spend $110 at the mall in 2 hours how much she can spend in three hours
To determine how long it took Julian to do his reading homework, we need to subtract the time he spent on math and science homework from the total study time.
First, let's convert the time spent on math and science homework into minutes:
Math homework: 45 minutes
Science homework: 35 minutes
Next, let's convert the total study time into minutes:
Total study time: 2 hours + 15 minutes = 2 * 60 minutes + 15 minutes = 120 minutes + 15 minutes = 135 minutes
Now, subtract the time spent on math and science homework from the total study time to find the time spent on reading homework:
Reading homework = Total study time - (Math homework + Science homework)
Reading homework = 135 minutes - (45 minutes + 35 minutes)
Reading homework = 135 minutes - 80 minutes
Reading homework = 55 minutes
Therefore, it took Julian 55 minutes to do his reading homework.
