Question

An insect is trying to climb on a high finishing smooth wall. Because of the high finishing of the wall, the insect slips down sometimes. The target of the insect is$11cm$ high in the wall from its initial position. If we denote his motion upside by a positive integer and downside by a negative integer, answer the following:

(i) If it crawls $8cm$ upside but slips down by making the $3cm$ in each of its moves, what is the position of the insect after two such moves.

Answer 1

As it is given that An insect is trying to climb on a high finishing smooth wall. Because of the high finishing of the wall, the insect slips down sometimes

Target $=11\mathrm{cm}\mathrm{high}\mathrm{in}\mathrm{wall}$

Insects crawl $8cm$ upside but slip down by making the $3cm$ in each of their moves

So, the position of the insect after two such moves is $+8-3+8-3=10cm$

Hence the position of the insect is $10cm$
