Question

1c.What is his new texting speed if he practices for 3 months

Answer 1

His new texting speed will be 3.5 characters per second this is because of the texting rate increasing per month is 0.5, just multiply that by 3 because there is 3 months than add that to 2 seconds

Answer 2

Answer:

$3\frac{1}{2}$ character per second.

Step-by-step explanation:

James current texting speed = 2 characters per second

Increase in texting speed with practice = $\frac{1}{2}$ a character per second per month.

If he practices for x months then the expression that will represent his typing speed = 2 + $\frac{1}{2}\times x$

If x = 3 months then his typing speed after 3 months will be

Speed = $2+\frac{3}{2}$

           = $\frac{4+3}{2}$

           = $\frac{7}{2}$

           = $3\frac{1}{2}$ character per second.

Therefore, after 3 months of practice his typing speed will be $3\frac{1}{2}$ character per second.
