The mean distance of Mars from the sun in `1.524` times that of the Earth from the sun. Find the number of years requires for Mars make one revolution about the Sun.

Explanation

For plantes revolving around the Sun `T^(2)propr^(3)`
`implies (T_(1)^(2))/(T_(2)^(2))=(r_(1)^(3))/(r_(3)^(2))=`
(`T_(1)=` time period of Mars,
`T_(2)=` time period of the Earth)
`implies(T_(1))/(T_(2))=((r_(1))/(r_(2)))^(3//2)impliesT_(1)=T_(2)((r_(1))/(r_(2)))^(3//2)=` (1 year) `(1.524)^(3//2)`
`=1.88`years
