Answer:
To determine which option covers the longest time, let's convert each time period into a consistent unit, such as days.
Given:
a. 100 weeks
Calculation:
\[ 100 \text{ weeks} \times 7 \text{ days/week} = 700 \text{ days} \]
b. 20 months
Assuming each month has 30 days (approximation for simplicity):
\[ 20 \text{ months} \times 30 \text{ days/month} = 600 \text{ days} \]
c. 1.5 years
Convert years to days (assuming a year has 365 days):
\[ 1.5 \text{ years} \times 365 \text{ days/year} = 547.5 \text{ days} \]
d. 800 days
This is already given in days.
Now, comparing the results:
- 700 days (option a)
- 600 days (option b)
- 547.5 days (option c)
- 800 days (option d)
Among these options, **800 days (option d)** covers the longest time period. Therefore, option d covers the longest time.
100 weeks = 700 days
20 months = around 610 days
1.5 years = around 548 days
which means 800 days is the longest
final answer = 800 days
20 months = around 610 days
1.5 years = around 548 days
which means 800 days is the longest
final answer = 800 days
