Question

The rule below shows how to calculate the average speed of a bicycle race.
Divide the race distance by the difference between the start time and finish time.
If S = average speed and d = race distance, which equation expresses the rule above?
A. S(d)=d/finish time + start time
B. S(d)=d/finish time-start time
C. S(d)=d/finish time - start time
D. S(d) = d/ finish time+start time

Answer 1

i need help on it.

Answer 2

by definition of average speed your answer is:
