A water tank has steps inside it. A monkey is sitting on the first step. The water level is at the ninth step. He jumps 3 steps down, and jumps back 2 steps. In how many jumps will he reach the water level?
Answers
Answer:
13 jumps
Step-by-step explanation:
monkey in the 1 step and water level is at ninth step so monkey jumps three step down and then jump back two step
1- 3
2- 3 2 3
3- 3 2 3 2 3
4- 3 2 3 2 3
5- 3 2 3 2 3
6- 3 2 3 2 3
7- 3 2 3 2 3
8- 3 2 3
9- 3
THIS PIC OF 3 JUMPS 3 STEPS DOWN
AND
THIS PIC OF 2 JUMPS BACK 2 STEPS
look at the pic and try to understand in your way
Answer:
let the step move down be represented by positive integers and and the step moved up be represented by negative integers
Step-by-step explanation:
1st jump, the the monkey be at step = 1+3=4
2nd jump, the the monkey be at step = 4+(-2) = 2
3rd jump, the the monkey be at step = 2+3 =5
4th jump, the the monkey be at step = 5+(-2) = 3
5th jump, the the monkey be at step = 3+3 =6
6th jump, the the monkey be at step = 6+(-2) =4
7th jump, the the monkey be at step = 4+3 =7
8t jump, the the monkey be at step = 7+(-2) =5
9th jump, the the monkey be at step = 5+3 = 8
10th jump, the the monkey be at step = 8+(-2) =6
11th jump, the the monkey be at step = 6+3 =9
clearly, the monkey will be at the water level( i.e 9) steps after 11 jump
