Answer:
The diver will use a total amount of 0.03 m³ in a minute
Step-by-step explanation:
Step 1: Determine number of breaths per minute
This can be expressed as;
Number of breaths=breaths per minute×number minutes
where;
breaths per minute=15
number of minutes=1
replacing;
Number of breaths=(15×1)=15 breaths
Step 2: Total volume of air used
This can be expressed as;
Total volume=volume per breath×number of breaths
where;
volume per breath=0.002 m3
number of breaths=15
replacing;
Total volume=(0.002×15)=0.03 m³
The diver will use a total amount of 0.03 m³ in a minute
