Question

Before enrolling in a typing course, Maria could type 35 words per minute. At the end of the course, she could type 77 words per minute. Find the percent of increase in her typing rate

Answer 1

Given:

Initial speed of typing = 35 words per minute

At the end of the course her typing speed = 77 words per minute

To find:

The percent of increase in her typing rate.

Solution:

We know that,

`\text{Percent of increase in her typing rate}=\frac{\text{New speed - initial speed}}{\text{Initial speed}}* 100`

`\text{Percent of increase in her typing rate}=(77-35)/(35)* 100`

`\text{Percent of increase in her typing rate}=(42)/(35)* 100`

`\text{Percent of increase in her typing rate}=120\%`

Therefore, her typing rate is increased by 120%.
