Answer:
112 hours and 50 mins
Step-by-step explanation:
Numbers of mins worked in a day = 7×60+30 =450 mins
Now number of mins worked in 15 days = 450×15
= 6750 mins
to convert mins into hours divide by 60
6750÷60 = 112.50
that means total number of hours worked in 15 days = 112 hours and 50 mins
(b+c)(x+3)
I hope this is true
2.000 pluse 4.00=600.000
