The speed is the distance covered by an object at a particular time. There exists no contrast between the two of the given conditions.
What is speed?
The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.
Speed = Distance/Time
The rate for the ratio of distance and time is known as speed. Therefore, the speed in both cases is needed to be calculated as shown below.
The rate when the distance covered is 4/5 miles and the time is 8 minutes,
Rate = Distance / Time
= 4/5 miles / 8 minutes
= 4/(5×8) miles per minute
= 4/40 miles per minute
= 0.1 miles per minute
The rate when the distance covered is 2/5 miles and the time is 4 minutes
Rate = Distance / Time
= 2/5 miles / 4 minutes
= 2/(5×4) miles per minute
= 2/20 miles per minute
= 0.1 miles per minute
Since the rate of the two conditions is the same, therefore, there exists no contrast in the two of the given conditions.
