To find out what day of the week it will be 120 days from Tuesday, we can calculate the remainder of 120 when divided by 7 since there are 7 days in a week.
First, we divide 120 by 7:
\[ 120 \div 7 = 17 \text{ remainder } 1 \]
This means that 120 days is equivalent to 17 weeks and 1 extra day. Adding that extra day to Tuesday:
- Tuesday + 1 day = Wednesday
So, 120 days from Tuesday will be a Wednesday.
