Question

The moon is 384,403 km from earth. Estimate how many quarters laid end to end it would take to reach the moon if a quarter has a diameter of .9055

Answer 1

The number of quarters is about
`16,713\ quarters`

Explanation:

we know that

The diameter of a quarter is 0.9055 in

The moon is 384,403 km from earth

To find out the number of quarters, divide the distance of the Moon from the Earth by the diameter of one quarter

step 1

Convert inches to kilometers

`1\ in=2.54*10^(-5)\ km`

`0.9055\ in=0.9055*2.54*10^(-5)=2.3*10^(-5)\ km`

step 2

Find the number of quarters

`384,403/2.3*10^(-5)=16,713\ quarters`
