If the computer solves $\frac{1}{200}$ questions in 1 second, then in 120 seconds, it will solve:

$\text{Questions solved in 120 seconds} = 120 \times \frac{1}{200} = \frac{120}{200} = \frac{3}{5} = 0.6$

Thus, the computer will solve 0.6 questions in 120 seconds.

Here are 5 related questions you might find interesting:

1. How many seconds will it take for the computer to solve 1 question?
2. How many questions can the computer solve in 1 minute?
3. If the computer solves $\frac{1}{300}$ questions per second, how many will it solve in 150 seconds?
4. How long will it take the computer to solve 5 questions?
5. What if the computer's speed is doubled? How many questions will it solve in 120 seconds?

Tip: To solve such problems, multiply the rate (questions per second) by the total time to find the number of questions solved.
