Answer:
6 Jumps
Step-by-step explanation:
For every step frog jump 3 m and fall back = 2 m
When frog reaches ≥ 9 m then his jump of 3m will make ≥ 12 m
so frog will be out of well.
For all other jumps frog will 3 - 1 = 2m
So for n number of jumps by frog
( n -1 ) * 2 ≥ 12 - 3 ( as there will be last jump 3m will make ≥ 12 m
so frog will be out of well.
For all other jumps frog will 3 - 1 = 2m
So for n number of jumps by frog
( n -1 ) * 2 ≥ 12 - 3 ( as there will be last jump also)
=> (n - 1) * 2 ≥ 9
=> 2n - 2 ≥ 9
=> 2n ≥ 11
=> n ≥ 11/2
=> n ≥ 5.5
=> n = 6
in 6 jumps Frog will be out of well
