Answer: 9.5 miles
Step-by-step explanation:
Given : A group of friends were on a hiking trip they plan to hike a total of 38 miles .
They want to complete 25% of the hike by the end of the first day .
We can write 25% as 0.25 in decimal.
Now, the number of miles they should hike the first day will be :-
[tex]0.25\times38=9.5\text{ miles}[/tex]
Hence, the number of miles they should hike the first day =9.5 miles
