Question

Braille because of its size and detail, Braille takes longer to read than text. A person reading Braille reads and the rate of 25% the rate of a person reading text.
a. Write and graph an equation that represents the average rate of y of Braille reader in terms of the average rate x of a text reader.

Answer 1

The relationship between the reading rate of text and Braille can be modeled in terms of t as B(t) = 0.25t

Let :

Text reading rate = t

Braille reading rate can be expressed in terms of t thus :

• B(t) = 0.25t

Therefore, we could make a proportional relationship table thus :

t = 1

B(t) = 0.25(1) = 0.25

t = 2

B(t) = 0.25(2) = 0.5

t = 3

B(t) = 0.25(3) = 0.75

0.75t = 4

B(t) = 0.25(4) = 1

1 t = 5

B(t) = 0.25(5) = 1.25

Text reading rate, t ; 1 ____ 2 ___ 3 ____ 4 ____ 5

Braille reading rate ;0.25_0.50_0.75 __1.00 __1.25

Therefore, the graph of the relationship between text and braille reading rate is attached below.
