Ariel (150 words per minute)

Step-by-step explanation:

We are given the different rate at which each student reads number of words against time.

To select which student reads the fastest (greatest number per minute), let's calculate for each student the number of words they can read per minute using the information given to us about the 3 students in the options.

==>Tamar:

Let "a" be the number of words Tamar reads per minute

500 words = 5 minutes

a = 1 minutes

Cross multiply

500*1 = 5*a

500 = 5a

500/5 = a

a = 100 words per minute.

==>Levi:

From the table given for Levi, he reads 280 words in 2 minutes

Let "b" be the number of words he would read per minute

280 = 2

b = 1

280*1 = 2*b

280 = 2b

280/2 = b

140 = b

b = 140 words per minute

==>Ariel:

From the graph given for Ariel, 300 words is read in 2 minutes.

Let c = words read per minute

300 = 2

c = 1

300*1 = 2*c

300 = 2c

300/2 = c

150 = c

c = 150 words per minute

The student that reads fastest is Ariel (150 words per minute)
