Answer

60

The correct answer is 60 — Finally, multiply ticks per second by total seconds: $0.5 \times 120 = 60$ ticks.

Step-by-step solution

First, convert 2 minutes into seconds: $2 \times 60 = 120$ seconds.
Next, find the number of ticks per second: $5$ ticks per $10$ seconds gives $5/10 = 0.5$ ticks per second.
Finally, multiply ticks per second by total seconds: $0.5 \times 120 = 60$ ticks.

Common mistake: Forgetting to convert minutes to seconds

Concept tested: Counting ticks in a given time interval
