One night Angel spent 2 hours and 41 minutes doing homework. She spent 43 minutes on math, 37 minutes on language arts, and half an hour on science. The rest of her time was spent on social studies. How much time did she spend on social studies?
she spend 60*2+41 minutes on homework: 161minutes
she spend on 43 min on math, 37 on language, and 60 min on science: total 140 min
so how much is left?
51
work:
60*2=120+41=161
43+37+30=110
161-110=51
45+35=80
To find out how much time Angel spent on social studies, we need to subtract the time she spent on math, language arts, and science from the total time she spent doing homework.
First, let's convert 2 hours and 41 minutes into minutes. Since there are 60 minutes in an hour, we get:
2 hours = 2 * 60 = 120 minutes
Now, add the minutes:
120 minutes + 41 minutes = 161 minutes
Next, subtract the time spent on math (43 minutes), language arts (37 minutes), and science (30 minutes) from the total time (161 minutes):
161 minutes - 43 minutes - 37 minutes - 30 minutes
Now, calculate:
161 minutes - 43 minutes = 118 minutes
118 minutes - 37 minutes = 81 minutes
81 minutes - 30 minutes = 51 minutes
Therefore, Angel spent 51 minutes on social studies.
