Matt can write 10 words a minute with his right hand and 7 words a minute with his left hand. How many words would Matt write in 5 minutes with his right hand than with his left?
The difference in writing speed is 10 words/minute - 7 words/minute = <<10-7=3>>3 words/minute
Matt can write 3 words/minute x 5 minutes = <<3*5=15>>15 more words with his right hand.
