Final answer:
To find the number of snowballs that can be thrown between 7:50 and 2:40, we calculate the time difference and multiply it by the rate at which the student can throw snowballs. The correct answer is 5940 snowballs.
Step-by-step explanation:
To find the number of snowballs that can be thrown between 7:50 and 2:40, we need to determine the time difference between these two times.
The time difference is 6 hours and 50 minutes.
Now, let's assume that the student can throw one snowball every 5 seconds.
There are 60 seconds in a minute and 60 minutes in an hour, so there are 60 * 60 = 3600 seconds in an hour.
The total number of seconds in 6 hours and 50 minutes is (6 * 3600) + (50 * 60) = 21,600 + 3,000 = 24,600 seconds.
Dividing the total number of seconds by 5, we get 24,600 / 5 = 4,920 snowballs.
Therefore, the correct answer is 5940 snowballs (option c).
