`1nm = 10^(-9)m`

`1000m = 1km`

`1m = 10^(-3)km`

`1nm = 10^(-9)xx10^(-3) = 10^(-12)km`

`1km = 0.621371mi`

`1nm = 10^(-12)xx0.621371mi = 6.21371xx10^(-13)mi`

`1nm = 6.21371xx10^(-13)mi`

`4.0 xx 10^20nm = 4.0 xx 10^20xx6.21371xx10^(-13)mi `

`4.0 xx 10^20nm = 2.4855xx10^8mi`

So the answer is `2.4855xx10^8mi`
