we can set up a division problem to determine how long it will take tyrone to type 1624 words. However, first we will need to determine how many words he can type in 1 minute.
87 words / 3 minutes = 29 words per minute
1624 words / 29 words per minute = 56 minutes
*notice how the final units is minutes because the unit “words” cancels out since it is found in both the numerator and denominator.*
hope this helps!
