Well. One kilometre ( or kilometer if you're from the US) is 5/8 of a mile therefore one mile is 8/5 kilometres. Therefore 141500000 times 8 is 1132000000 and divided by 5 is 226,400,000 kilometres. To convert 687 days to years, divide by 365 ( assuming not a leap year!) so 687/365 is 1.882191 years.

141,500,000 miles is 229,230,000 kilometers. As for the 687 days that is equal to 1 Mars years or 1.88 Earth years. Mars travels 205,967 miles per day or 333,668 kilometers per day in it's travel around the sun.

what is this question doing in chemistry????
however coming to the question, to convert miles into kms u should multiply th value by 1.6 so that 1 mile is 1.6 km now u can solve that bit
687 days is 687/365 years what's wrong???
