You run from your house to a friend's house that is 4 km away. You then walk home. What distance did you travel? What was the displacement for the entire trip? Draw a picture to help you find the answer. * 9 points Distance 8 km, Displacement 8 km Distance 0 km, Displacement 8 km Distance 0 km, Displacement 0 km Distance 8 km, Displacement 0 km

C

Displacement 0 km Distance 8 km,

Explanation:

Given that You run from your house to a friend's house that is 4 km away. You then walk home. Either you run or walk both displacement and distance covered are concerned about the length covered.

The distance will be only the magnitude of the length covered.

The distance = 4 + 4 = 8km

While the displacement will comprise the magnitude of the length covered by considering the direction

Displacement = 4 - 4 = 0

Therefore, the correct answer is

Displacement 0 km Distance 8 km,

Which is option C

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
