Problem Analysis

We are given that Uncle Fyodor's step is three times longer than Matroskin's step. Matroskin walked along a straight road first, and then Uncle Fyodor started from the same place as Matroskin. Uncle Fyodor erases the footprints left by Matroskin as he steps on them. Then Sharik walks and counts 17 steps of Matroskin. We need to determine how many footprints Uncle Fyodor left on the road.

Solution

Let's assume that Matroskin took x steps along the road. Since Uncle Fyodor's step is three times longer, he took 3x steps. Sharik counted 17 steps of Matroskin, so we can set up the equation:

x + 3x - y = 17

Where y represents the number of footprints left by Uncle Fyodor.

Simplifying the equation, we get:

4x - y = 17

To find the value of y, we need to find the value of x. We can do this by solving the equation using the information given.

Since Matroskin walked along a straight road, the number of steps he took is equal to the number of footprints he left. Therefore, we can substitute x for the number of footprints left by Matroskin.

Let's solve the equation to find the value of y.

Calculation

Substituting x for the number of footprints left by Matroskin, the equation becomes:

4x - x = 17

Simplifying further:

3x = 17

Dividing both sides by 3:

x = 17/3

So, Matroskin left approximately 5.67 footprints on the road.

Now, let's substitute this value back into the equation to find the number of footprints left by Uncle Fyodor.

4(17/3) - y = 17

Simplifying:

(68/3) - y = 17

To isolate y, we subtract (68/3) from both sides:

-y = 17 - (68/3)

Simplifying further:

-y = 51/3

Dividing both sides by -1:

y = -51/3

So, Uncle Fyodor left approximately -17 footprints on the road.

Answer

Based on the given information, Uncle Fyodor left approximately -17 footprints on the road.
