Question

Help! How would I solve this? Sound travels in x seconds and the distance d, in miles, can be modeled by the equation d=0.3x, how many seconds would it take to hear an airplane that is 5 miles away?

Answer 1

1.5 seconds

Answer 2

It's a multiple choice question, but I don't see 1.5 for an answer?

Answer 3

d = 0.3x
where d is distance and x is time. Would you substitute the 5 for the d or x?

Answer 4

The x?

Answer 5

d represents distance and 5 miles is a distance, not a time.
5 = 0.3x

Answer 6

Now divide both sides by 0.3

Answer 7

Would it be 16.67?

Answer 8

yes

Answer 9

Awesome! Thank you.
