Answer:
2.84 KM/h
Explanation:
let initial position of boy Xo= 0 KM
when he travel 10KM in east X1=10Km
when he travels 2.5 KM in west X2= 2.5 KM
total displacement = 10 - 2.5= 8.5KM
total time taken = 2+1 = 3 hours
average velocity = total displacement / time
average velocity = 8.5/3
average velocity = 2.84 km/h
