Answer:
4.4 hours
or
4 hours 24 minutes
Step-by-step explanation:
Remember that
1 hour=60 minutes
step 1
Convert the amount of time each week for a month in minutes
so
a) 1 hour 3 minutes
[tex]60+3=63\ min[/tex]
b) 1 hour 18 minutes
[tex]60+18=78\ min[/tex]
c) 55 minutes
d) 68 minutes
step 2
Adds the minutes
[tex]63+78+55+68=264\ min[/tex]
step 3
Convert to hours
Divide by 60
[tex]\frac{264}{60}= 4.4\ hours[/tex]
step 4
Convert to hours and minutes
[tex]4.4\ h=4\ h+0.4(60)\ min=4\ h+24\ min[/tex]
