Answer: It traveled 0.06172 km.
Step-by-step explanation:
Given: Speed of block = 4 m/s
Time taken by block = 15.43 s
To calculate: Distance covered by it in km.
We know that,

So distance covered by block = 
= 
Since 1 kilometer = 1000 meters.
So,

Hence, it traveled 0.06172 km.
If you want the answer in point slope form then,
y-y1 = m(x-x1)
y-c = m(x-a)
---------------------------------------
If you want the answer in slope intercept form, then solve for y
y-c = m(x-a)
y-c = mx-ma
y-c+c = mx-ma+c
y = mx-ma+c
y = mx+c-ma
y = mx+(c-ma)
For this answer in slope intercept form the slope is m and the y intercept is c-ma
---------------------------------------
If you want the answer in standard form, then get the variable terms to the left side. Have the constant terms on the right side.
y = mx+c-ma
y-mx = mx+c-ma-mx
-mx+y = c-ma
Optionally you can multiply both sides by -1 to get mx-y = -c+ma but it will depend on your book if this step is carried out or not.
~Hello There!~
Multiplier = 0.02
8/0.02 = 400
The number is 400.
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^
