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

Correct answer:

x =  26 km

Step-by-step explanation:

x+(x1.5)+(x3)+(x4.5)+(x6)=115 x=26 km

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

5x = 130

x = 130/5 = 26

x = 26
