Philosophy doesn't just tell us what to believe. It also helps us improve our thinking by improving our ability to be reasonable. This isn't just by having rules that tell us what forms of reasoning are appropriate, like we learn in logic classes.

Melanie observes a marble travel along a horizontal path at a constant rate. The marble travels 1/30 of the length of the path i

Answer: 67.5 seconds

Explanation:

The marble is traveling at a speed of 1/30 length units per 2.25 seconds.

Use direct proportion to find out the amount of time it would take to cover the whole length:

1/30 : 2.25 seconds

1 : x

1/30 x = 2.25 seconds

x = 2.25 ÷ 1/30

x = 2.25 * 30/1

x = 67.5 seconds

67.5 seconds is 1 mins and 7¹/₂ seconds.
