Answer 1

Answer:

Luis finishes 5 minutes faster than Shelia

Step-by-step explanation:

Sheila types 120 words in 4 minutes  The other point is 0 words in 0 minutes

The slope is ( 120 words / 4 minutes = 30 words per minute)

w = 30t

Luis types w = 40t or 40 words per minute

They each need to type a 600 word essay

Shelia

w = 30t

600 = 30t

600/30 =t

20 =t

It will take Sheila 20 minutes

Luis

w = 40t

600 = 40t

600/40 =t

15 =t

It will take Luis 15 minutes

Shelia - Luis = 20 -15 minutes = 5 minutes

Luis finishes 5 minutes faster
