Is there a grid that came with the problem?
Answer:
20 hours.
Step-by-step explanation.
The total distance traveled was 400 miles. Then I divided 400 by 20. I got 20.
To find how long it would take him, one has to divide 400 by 160 and then multiply 5 by what that number is. You multiply 5 by the quotient because that is the number that would make it proportional. 400/160 x 5 is 12.5, meaning that the answer is 12.5 minutes, or A.
