Answer:
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)
