Question

Ignacio can type 55 words per minute (wpm).in 5 minutes, she types 285 words. how many errors would you expect her to make?

Answer 1

55 x 5 = 275 words
285 - 275 = 10
10 errors would be expected

Answer 2

The number of errors would I expect her to make is:

• 10 errors.

Explanation:

Since it is mentioned that the person can write 285 words in five minutes, a division is performed to identify the actual number of words written per minute (wpm).

• 285 / 5 = 57 wpm

However, it had previously been mentioned that she wrote 55 wpm, so a subtraction is performed to identify the number of misspelled words per minute:

• 57 - 55 = 2

As it is identified that the person misspells two words per minute, this value is multiplied by the time span taken into account (5 minutes):

• 2 X 5 = 10

Providing a value of 10 misspelled words every five minutes or two misspelled words every minute.
