Question

The average distance from the earth to the moon is 3.844 x 10⁸ meters. If the length of the average pencil is 1.8 x 10⁻¹ meters, approximately how many pencils would need to be connected together to reach the moon?

Answer 1

To calculate how many pencils are needed to reach the Moon, the distance from Earth to the Moon (3.844 x 10⁸ meters) is divided by the length of an average pencil (1.8 x 10⁻¹ meters), resulting in approximately 2.135 x 10⁹ pencils.

Step-by-step explanation:

The average distance from the Earth to the Moon is 3.844 x 10⁸ meters. To find out how many average pencils, which have a length of 1.8 x 10⁻¹ meters, we would need to connect together to reach the Moon, we use division:

1. First, we take the Earth to Moon distance: 3.844 x 10⁸ meters.
2. Then, we divide that by the length of one pencil:1.8 x 10⁻¹ meters.
3. So, 3.844 x 10⁸ m / 1.8 x 10⁻¹ m = 2.135 x 10⁹ pencils.

This means that you would need approximately 2.135 x 10⁹ pencils to reach from the Earth to the Moon.
