during manoeuvers on a space walk,an astronauts pulse rate first rose 48 beatsper minut,then fell 15 beats per minute,rose 32beats per minute and after the astronauts return to the capsule fell 50 beats per minute.what is the net change in his pulse rate?
Answers
Given : ‘an astronaut ‘s pulse rate rose 48 beats per minute, then fell 15 beats per minute, again rose by 32 beats per minute, and after the astronaut’s return to the capsule, fell 50 beats per minute.
To find : net change in his pulse rate
Solution:
rose 48 beats per minute
fell 15 beats per minute,
rose by 32 beats per minute
fell 50 beats per minute.
Total Rise = 48 + 32 = 80 beats per minute
Total fall = 15 + 50 = 65 beats per minute
Net Rise = 80 - 65 = 15 beats per minute
net change in his pulse rate = 15 beats per minute

To Find :
- net change in his pulse rate
Solution :
total no. of beats rise = 48 + 32 beats
⇒ total no. of beats rise = 80 beats
_____________________
Total no. of beats fall = 15 + 50 beats
⇒ Total no. of beats fall = 65 beats
_____________________
Change in pulse rate = 80 - 65
⇒ Change in pulse rate = rise of 15 beats
★ Change in pulse rate is rise of 15 beats
