Question 537: A family is making a trip which will cover 5200 miles. After three days travel time, the family has covered 4/13 of the distance. They have ten more days to complete the trip. How many miles per day should they average for the remainder of their trip?

Well, first we need to work out how far they have travelled so far:
%284%2F13%29+%2A+5200+=+1600
Take that away from the total trip gives us the remaining distance:
5200+-+1600+=+3600
They have 10 days to cover 3600 miles, and we want to know how far they need to travel in 1 day:
3600+%2F+10+=+360
Therefore they need to travel an average of 360 miles a day for the remainder of the trip.
