Question

An ice cream machine produced 52 ice creams per minute. After reconditioning, its speed increased to 65 ice creams per minute. By what percent did the speed of the machine increase?

Answer 1

Step-by-step explanation:

Old speed of ice cream machine= 52/min

New speed of ice cream machine= 65/min

Increase in speed= (65-52)/min

=13/min

So, percent increase= increase in value/original value × 100%

=(13/52×100)%

=25%
