# Scouts

The boys from scout group traveled 5 days distance 115 km. Every day walked 1.5 km less than the previous day. How many kilometers scouts walked in the first day?

Correct result:

x =  26 km

#### Solution:

$x+(x-1.5)+(x-3)+(x-4.5)+(x-6) = 115 \ \\ x = 26 \ \text{km}$

x+(x-1.5)+(x-3)+(x-4.5)+(x-6) = 115

5x = 130

x = 26
