Step-by-step explanation:

Answer:

500 miles

Step-by-step explanation:

80% is converted to its decimal form 0.8

Multiply 0.8 times "x" which is the unknown total distance of the trip (80% of the total trip) to get 400 because 80% of the trip is 400 miles. Then find x

0.8x = 400

400/0.8 = x

500 = x
