Answer 4
Average velocity is given as
Average Velocity = total distance / total time
now it is given that
d = 12.2 miles
t = 3.4 hours
now we will use the above equation
So average speed is 3.6 mph
Answer 5
Average velocity is given as
Average velocity = total displacement / total time
now given that
total displacement = 8 miles
total time taken = 0.25 hours
now by above formula
So average velocity is 32 mph
