Answer:
The couple rests 36 minutes in 8 hours
Step-by-step explanation:
Step 1: Determine the total amount of time couple rests in an hour
The total amount of time the couple rests in an hour can be expressed as;
T=t×h
where;
T=total amount of time the couple rests in 6 hours
t=amount of time couple rests per hour
h=number of marathon hours
In our case;
T=27 minutes
t=unknown
h=6 hours
replacing;
27=t×6
t=27/6=4.5 minutes per hour
Step 2: Determine the total number of hours the couple rests in 8 hours
The total amount of time the couple rests in 8 hours can be expressed as;
T=t×h
where;
T=unknown
t=4.5 minutes per hour
h=8 hours
replacing;
T=4.5×8=36 minutes
The couple rests 36 minutes in 8 hours
