Question

Before taking a typing course a candidate could type 16 words per minute. By the end of the course, the candidate was able to type 38 words per minute. Find the percent increase

Answer 1

137.5%

Step-by-step explanation:

V1 = speed of typing before joining the course = 16 words per minute.

V2 = speed of typing after end of the course = 38 words per minute.

The percentage increase in the typing speed is:

= ( V2 - V1 )/ V1 multiple by 100

= ( 38 - 16 )/ 16 multiple by 100

= 11/8 * 100

= 275/2

= 137.5%
