welcome to QC~ for a) you are given miles per hour and you want one light year which is essentially miles per year so you'd have to multiply 6.7x10^8 miles per hour * the number of hours in a year one year = 365 days; 1 day = 24 hours therefore one light year --> 6.7x10^8 * 365 * 24

Vocaloid:

for b) 1 mile = 1609.344 meters, so you'd multiply the result from part a) times 1609.344 meters
