This is another easy question, as long as you know your measurements.
1 mile = 5,280 feet
So, since 5,280 feet and one mile are the same thing, you can choose to use feet as your measurement, since it is the same as your question.
Use fraction to express your answer: 400/5280 miles
Use decimal to express your answer (same thing as a fraction only you divide the top number by the bottom number): 0.07575757575... or rounding it: simply 0.076 miles <--this is the best answer to use, and I bet this is what your teacher wants you to write the answer as.
Easy peasy lemon squeezy!
