Answer:
30 miles
Step-by-step explanation:
Given that:
Alex has some target to run a certain number of miles by the end of the month.
Goal already achieved = 40% of the total goal
Number of miles already run by Alex = 12 miles
To find:
Number of miles that Alex is trying to run by the end of month?
Solution:
We have to find nothing but the goal of Alex here.
Let the number of miles that Alex is trying to run by the end of the month =
miles
As per question statement:
40% of total number of miles to be run = 12 miles
OR
![\dfrac{40}{100}\times x = 12\\\Rightarrow 40x=12\times 100\\\Rightarrow x = \dfrac{1200}{40}\\\Rightarrow \bold{x = 30\ miles}](https://tex.z-dn.net/?f=%5Cdfrac%7B40%7D%7B100%7D%5Ctimes%20x%20%3D%2012%5C%5C%5CRightarrow%2040x%3D12%5Ctimes%20100%5C%5C%5CRightarrow%20x%20%3D%20%5Cdfrac%7B1200%7D%7B40%7D%5C%5C%5CRightarrow%20%5Cbold%7Bx%20%3D%2030%5C%20miles%7D)
Total number of miles that Alex is trying to run by the end of the month = <em>30 miles</em>
