Question

The smaller moon of Mars, Deimos, has a diameter of 7.5 miles. The larger moon, Phobos, has a diameter that is 1 3 4 times greater. What is the diameter of Phobos?

Answer 1

Answer: 13.125 miles.

Explanation:

Given : The smaller moon of Mars, Deimos, has a diameter of 7.5 miles.

The larger moon, Phobos, has a diameter that is
`1\frac34` times greater.

Diameter of Phobos =
`1\frac34*\text{(Diameter of Deimos )}`

`=(7)/(4)*7.5 \ \ \ [1\frac34 =(7)/(4)]\\\\=13.125\text{ miles}`

Hence, the diameter of Phobos = 13.125 miles.
