Given:

The planet Mercury is roughly $\dfrac{2}{5}$ the size of Earth.

The planet Jupiter is 2.5 times the size of earth.

Earth = 3,959 miles.

To find:

How much larger is Jupiter than Mercury?

Solution:

The planet Mercury is roughly $\dfrac{2}{5}$ the size of Earth.

$Mercury=\dfrac{2}{5}\times 3959$

$Mercury=1583.6$

The planet Jupiter is 2.5 times the size of earth.

$Jupiter=2.5\times 3959$

$Jupiter=9897.5$

Difference between size of Jupiter and mercury is

$9897.5-1583.6=8313.9$

Therefore, Jupiter is 8313.9 miles larger than Mercury.
