When Legs jumps 2 times and takes 13 steps forward, he lands in the same place as when he jumps 4 times and takes 5 steps backwa
tangare [24]

Answer:

9 steps

Step-by-step explanation:

Let x be the number of jumps

and y be the number of steps

So the first case

2x+13y

Second case

4x-5y

Both cover equal distances so

2x+13y=4x-5y

\Rightarrow 2x-4x=-5y-13y

\Rightarrow 2x=18y

\Rightarrow x=9y

So, one jumps is 9 steps.
