Final answer:
The rate at which expert video game players make moves is 10 moves per second. In 17 seconds, an expert video game player can make 170 moves.
Step-by-step explanation:
To find the rate at which expert video game players make moves, we divide the total moves made by the total time taken. So, the rate is 380 moves / 38 seconds = 10 moves per second.
To calculate how many moves an expert video game player can make in 17 seconds, we multiply the rate by the time. So, 10 moves/second × 17 seconds = 170 moves.
