Question

The distance from Earth to the moon is about 4×10^5 kilometers. The distance from Earth to Mars is about 5×10^7 kilometers. Use this data to compare the distances and complete the sentence. ​The distance from Earth to Mars is times greater than the distance from Earth to the moon.

Answer 1

To calculate the comparative distance from Earth to Mars and Earth to the moon, divide 5×107 km by 4×105 km, resulting in a factor of 125. Hence, the distance to Mars is 125 times greater than that to the moon.

Step-by-step explanation:

To compare the distances from Earth to the moon and from Earth to Mars, we use the given information: the distance to the moon is about 4×105 kilometers, and the distance to Mars is about 5×107 kilometers. To find out how many times greater the distance to Mars is compared to the moon, we divide the distance to Mars by the distance to the moon:

Distance to Mars / Distance to Moon = (5×107 km) / (4×105 km)

This simplifies to (5/4)×10(7-5), which equals 1.25×102, or 125. Therefore, the distance from Earth to Mars is 125 times greater than the distance from Earth to the moon.
