Answer: on the first day, they hiked 9 miles.

On the second day, they hiked 16 miles.

Step-by-step explanation:

Let x represent the distance that the two hikers hiked from the first mountain to the second mountain.

Let y represent the distance that the two hikers hiked from the second mountain to the hollow.

The total distance is 25mi. This means that

x + y = 25 - - - - - - - - - - - - - -1

If the distance between the second mountain and the hollow is 7mi more than the distance from the first mountain to the second mountain, it means that

y = x + 7

Substituting y = x + 7 into equation 1, it becomes

x + x + 7 = 25

2x = 25 - 7

2x = 18

x = 18/2 = 9

y = x + 7 = 9 + 7

y = 16

Sergei says that 10% of a number will always be less than 20% of any other number.
Zanzabum
That statement is only true sometimes.  If you use 500 and 10, 10% of 500 is 50, while 20% of 10 is only 2.  Clearly, 50 is larger than 2.
