Relationship between distance and time is A. d = 0.12m
Step-by-step explanation:
For an object moving in uniform motion (=constant velocity), the relationship between distance covered and time taken is given by
where
d is the distance
v is the velocity
t is the time
Therefore, in order to find the relationship between distance and time, we have to find the velocity of the train.
This can be done by using the data of the table: in fact, the velocity is the ratio between the distance covered and the time taken to cover that distance.
Therefore, if we take for instance the last point of the table:
d = 2.4 miles (distance covered)
t = 20 minutes (time taken)
So the velocity is
And therefore, the relationship between distance and time is
(where m is the time in minutes)
