Benji types twice as fast as Trisha, who types 200 words in 4 minutes. This means Benji can type 200 words in half the time it takes Trisha, or 2 minutes. To find Benji's typing speed, divide the number of words he types (200) by the time it takes him (2 minutes):
Benji's typing speed = 200 words / 2 minutes = 100 words per minute
So, the rate that best represents Benji's typing speed is B: 100 words per minute.
