Question

What is the correct definition of speed?

A. time (hours or seconds)
B. time per distance (hours per mile or seconds per meter)
C. distance per time (miles per hour or meters per second)

Answer 1

C

Step-by-step explanation:

The correct definition is distance / time, although teachers like to mix you up sometimes. A question like "How many minutes per mile does it take to go 3miles in 20 minutes?" In this question, the units are upside down.

The standard answer is what is the rate of speed when when 3 miles are covered in 2 hours.

Here the answer is 3/2 = 1.5 miles / hour which is the standard way of writing speed or rate. distance / time.
