Final answer:
By setting up a proportion and multiplying the average words typed in 5 minutes by the number of 5-minute intervals in half an hour, we determine that Pat can type 1110 words in half an hour.
Step-by-step explanation:
Calculating Words Typed in Half an Hour
If Pat can type an average of 185 words in 5 minutes, to find out how many words Pat can type in half an hour, we need to set up a proportion. Since half an hour is equal to 30 minutes, we first need to determine how many 5-minute intervals there are in 30 minutes. There are 6 intervals of 5 minutes in 30 minutes.
Next, we multiply the number of words Pat can type in one 5-minute interval (185 words) by the number of intervals in 30 minutes (6 intervals):
185 words x 6 = 1110 words
Therefore, Pat can type 1110 words in half an hour at the given typing speed.
