Answer:

5.36 times bigger

Explanation:

The radius of the Earth is:

$r_e = 6371 km$

so its diameter is

$d_e = 2 r_2 = 12742 km$

The radius of Pluto is:

$r_p = 1188 km$

So its diameter is

$d_p = 2 r_p = 2376 km$

So the ratio between the two diameters is

$\frac{d_e}{d_p}=\frac{12742 km}{2376 km}=5.36$

So the diameter of the Earth is 5.36 times bigger than the diameter of Pluto.

Julia walks from the park, which is six blocks east of her house, to the store, which is three blocks east of her house. Julia walks for 5 minutes. This walk's average speed will be 1.2 blocks per minute. Option B is correct.

<h3>What is displacement?</h3>

Displacement is defined as the shortest distance between the two points. Distance is the horizontal length covered by the body. While displacement is the shortest distance between the two points.

Displacement is a vector quantity .its unit is m.

The average velocity on this walk will be;

$\rm v_{avg}= \frac{d}{t} \\\\ \rm v_{avg}= \frac{6 \ block+ 3 \ block }{5 \ minute } \\\\ v_{avg}=1.4 \ block /min$
