The rest of the day is twice as long as the last part. What time is it now?
September 4, 2021 | education
| Let’s express the rest of the day in t, then the past part will look like this: t / 2. There are 24 hours a day. Now we compose an equation and solve it:
t + t / 2 = 24;
2t / 2 + t / 2 = 24;
3t / 2 = 24;
t * 3/2 = 24;
t = 24: 3/2;
t = 24 * 2/3;
t = 16 hours – the rest of the day.
Let’s calculate the elapsed part of the day:
t / 2 = 16/2 = 8 hours – the past part of the day.
Since the day starts at 00 o’clock, we will calculate what time it is now:
0 + 8 = 8 o’clock – morning time is now.
Answer: it is 8 o’clock in the morning now.
