If the heart is beating at 76. 0 beats per minute, the Frequency of heart's oscillations in hertz is 1.25 Hertz.
The Frequency is defined as the number of oscillations completed in 1s.
Our heart beats continuously giving rise to the frequency of the heart.
Measuring frequency would be possible if we measure the time in seconds.
75 beats per minute means that 75 beats occur in 60s.
Frequency = Number of beats / Total time taken
Frequency = 75 / 60
Frequency = 1.25 Hz
Hence, number of beats per second is 1.25 Beats.
Beats per second or Cycles per second is same as the frequency of oscillation called as Hertz (Hz)
Hence, frequency of the heart oscillation is 1.25 Hertz (Hz).

Answer:
Calculate using the formula
Explanation:
velocity= displacement (m)/time(s)
1 mile =1.6km
1km=1000m
26.5, I’m not sure if it’s right but 1060/40 gets that
As it is a position time graph
So, it's slope represents velocity
During last 15 seconds
it passes through (5,17) (20,2)
Slope = -15/15 = -1
So Velocity= -1 m/s
