Seven poles A, B, C, D, E, F and G are put in such a way that the distance between the next two decreases by 1 metre. The distance between the first two poles, A and B,is 10 metres, Now answer the following questions?
According to the problem, the distance between poles are
A to B = 10 m
B to C = 9 m
C to D = 8 m
D to E = 7 m
E to F = 6 m
F to G = 5 m
$$\therefore\ $$The distance between the first pole A and the last pole G = 10 + 9 + 8 + 7 + 6 + 5 = 45 m
