Answer 1

Explanation:

If the descent starts from 10 m above the ground level, how long will it take to reach – 350 m. Thus, the elevator will reach -350 m from 10 m in 1 hour.

Answer 2

Answer:

A'B C + A B'C + A B C'+ A B C

Since We can use ABC = ABC + ABC So I use three of Copies:

A'B C + A B'C + A B C' + A B C + A B C + A B C

RE-ARRANGE: A'B C + A B C + A B'C + A B C + A B C'+A B C

GROUPING: BC(A'+A) + AC(B'+B) + AB(C'+C)

Since A'+A=1 & B'+B=1 & C'+C=1;

= BC+AC+AB
