Question

The circumference of the planet Jupiter is approximately 2.7 x 10^4 miles, while the circumference of the Moon is 6.75 x 10^3 miles. How many times longer is the circumference of Jupiter than the circumference of the Moon?

a) 4 times
b) 2 times
c) 10 times
d) 1/4 times

Answer 1

The circumference of Jupiter is four times longer than that of the Moon. To find this, divide 2.7 x 10^4 miles (Jupiter's circumference) by 6.75 x 10^3 miles (Moon's circumference), which equals four.

Step-by-step explanation:

To determine how many times longer the circumference of Jupiter is compared to that of the Moon, we divide the circumference of Jupiter by the circumference of the Moon:

• 
  
• 
  

Now, we calculate the ratio:

Ratio = (2.7 x 104) / (6.75 x 103)

This simplifies to:

Ratio = (2.7 / 6.75) x (104 / 103)

Ratio = 0.4 x 101

Ratio = 4

The circumference of Jupiter is four times longer than that of the Moon, so the answer is (a) 4 times.
