Tim can type 30 words in 34 of a minute. Justin can type 32 words in 45 of a minute.

How many words can Tim and Justin type altogether in 5 minutes?

Okay.

3/4 of one min = 45 sec.

4/5 of one minute = 48 sec.

To get Tim's count per minute, divide 30 by 45 (for count per second), then multiply by 60. For one minute, Tim can type 40 words.

Justin - (32/48) * 60. Justin can also type 40 words per minute.

Multiply both word counts by five (five minutes) then add them together. 200+200=400. Your answer is 400.
