Question

a worm is 30 feet deep in the well.every day he climbs 3 feet up the walls of the well but slips down 2 feet at night,as the walls become damp .how many days will it take to climb out

With steps integers

Answer 1

In one day the worm climb is = 3-2 feet
=1 feet
so total distance to be traveled is =30 feet
1 feet can be covered in 1 day
so 30 feet can be covered in 30 X 1 days
= 30 days
therefore to cover 30 feet we need 30 days
