On his trip from A to B, Julio covered the first 'x' miles @50 miles/hour and the remaining @60 miles/hour.How long did it take Julio to drive the first x miles?

1) Julio drove a total distance of 530 miles in 10 hours
2) It took Julio 4 more hours to drive the first 'x' miles than the remainder of the journey

Ans is A
from 1 we know the total distance covered so an equation could be formed as below x/50 + (530-x)/60 = 10 an d we can solve for x

from 2 we know only the difference in time which is not sufficient
