Rocky bikes 0.4 mile from his home to a park. Then he bikes from the park to the library to meet his friend Josie. If Rocky bikes a total distance of 3.86 miles, how far is the library from the park, in miles?

Dang i wish i could , good luck (i’m bad at math)

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
