Question

Raul drove 80 miles. This represents 50% of his entire trip. What is the total number of miles in Raul's trip?

Answer 1

If 80 miles is 50% of his trip, then you know that 80 miles is only HALF of his entire trip. To get the distance Raul traveled in total, simply double the 80 miles. This would be 160 miles. 
Raul traveled a total of 160 miles in his trip.
