An ant decides to climb a 30 feet wall. It climbs up 3 feet every hour, but slides back down 2 feet. How many hours does it take to reach the top of the wall?
Answers
Answer:
Step-by-step explanation:
As it takes 1 hour to travel an actual distance of 1 feet. It will take 27 hours to travel 27 ft. But in next hour it will travel 3 ft and reach top of the wall. So 28 hours should be the answer
The time taken by Ant to reach the top = 30 hrs
Given:
An ant decides to climb a 30 feet wall.
It climbs up 3 feet every hour, but slides back down 2 feet.
To find:
How many hours does it take to reach the top of the wall
Solution:
Given length of the wall = 30 feet
Ant will climbs 3 feets every hour
then back down 2 feets
Then the distance moved by Ant in 1 hour = 3 - 2 = 1 feet
The time taken by Ant to climb 1 feet = 1 hr
Then the time taken by Ant to reach the top = 1 hr × 30 = 30 hrs
The time taken by Ant to reach the top = 30 hrs
