Question

The mean distance of the earth from the sun (let's call it d) is 93 million miles. The distance varies as much as 1.6 million miles. Write the equation that describes the possible distances of the earth from the sun, using as distance unit millions of miles.

Answer 1

Kindly check explanation

Explanation:

Given that :

Mean distance of earth from the sun = 93 million miles

Let mean distance of earth from the sun = d

The variation on the distance is as much as 1. 6 million miles

Possible distances of the earth from the sun can be modeled using :

|d - 93| = ± 1.6

Where d = distance from earth to the sun

d = - 1.6 million + 93 million

d = 91.4 million

d = 1.6 million + 93 million

d = 94.6 million

Hence, possible distance from earth to the sun :

91.4 < d < 94.6
