A nurse worked from 8:15 A.M. until 11:30 A.M. and
12:30 P.M. until 4:15 P.M. Estimate the total number
of hours worked
A 7 hr
B 7 hr 30 min
C 7 hr 45 min
D 8 hr
the answer is a because 8:15 am to 11:30 am is 3 hours and 15 minutes. 12:30 pm to 4:15 pm is 3 hours and 45 minutes. 45 mins + 15 mins = 60 mins which is an hour. 3 hrs + 3 hrs + 1 hr = 7 hrs
