The puppy needs to catch a train that is moving at 8km/hr. she is 100 meters away and running at 10km/hr. How far will the train have traveled before the puppy is able to jump on?

The rabbit will jump on the train after the train moves 0.4km

The given parameters are:

-- distance between the puppy and the train

-- the speed of the train

--- the puppy's speed

Required

The distance where the puppy catch up with the train

First, we calculate the relative speed (rs) of the puppy to the train

Calculate the time to catch up with the train using:

Convert km to m

Calculate the distance to catch up with the train using:

--- speed of the train multiplied by the time

So, we have:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
