Given the statement:
Three months ago Santos could walk to miles in 40 minutes today he can walk to miles in 25 minutes
Determine the percent of change.
Solution:
In order to determine the percent of change in terms of time, we subtract 25 to 40, then divide the difference by 40.
= 40 minutes - 25 minutes
= 15 minutes
= 15 minutes/ 40 minutes
= 0.375
Since we are given a decimal answer, in order to convert it into percentage, we multiply the decimal by 100. Hence, in converting a percentage into decimal, we divide the percentage by 100.
= (0.375)(100)
=37.5%
Final answer:
The percent of change is 37.5%
