Question

How long would it take a plane to go 12.75 mile if it’s going 0.15 seconds per mile

Answer 1

Answer:

  1.9125 seconds

Step-by-step explanation:

The units give you a clue as to the math needed.

  (12.75 mi)×(0.15 s/mi) = (12.75×0.15) s = 1.9125 s

It would take 1.9125 seconds to go 12.75 miles.

Additional comment

You notice that miles are in the numerator of the distance, and the denominator of the given rate. That means those units will cancel when the numbers are multiplied. The remaining units will be seconds, the unit in the numerator of the given rate. That is what the problem is asking for.
