Question

An insect climbs a 15 m long pillar with 3 m in 1 h and 30 min rest, in rest time it falls 2 m then find time to climb 15 m pillar.

Answer 1

Answer:

⇒ The time to climb 15 m pillar = 22 hours and 30 minutes

Explanation:

The question is like a puzzle.

Height of the pillar = 15 m

The Insect climbs 3 m in time = 1 hr

Then it takes rest for 30 minutes and falls 2m back in this time.

So actually it covers 1 m in 1 hour an 30 minutes or 1.5 hours

It covers a distance of 1 m in time = 1.5 hr

It covers a distance of 15 m in time = 1.5 × 15 hr = 22.5 hr

⇒ The time to climb 15 m pillar = 22 hours and 30 minutes
