How much time does it take for an object moving at a speed of 5 m/s to move 20 meters?

ANSWER :

Time taken to cover 5 meter = 1 second

Time taken to cover 1 meter = ⅕ second

Time taken to cover 20 meter = ⅕ × 20

= 4 seconds

  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.
