Vanessa typically works 8 hours per day in a normal 5 day work week. Last week, however, Vanessa had to take 90 minutes off on Tuesday, 45 minutes off on Thursday, and she left two and a half hours early on Friday. How many hours did Vanessa work last week?
(A.35 hours 15 minutes)
B.35 hours 30 minutes
C.35 hours 45 minutes
D.36 hours 15 minutes
Is this correct? if so can you explain howd you got the answer?
90 minutes = 1.5 hrs
45 minutes = 0.75 hrs
1.5 + 0.75 + 2.5 = 4.75 hours
40 - 4.75 = 35.25 = 35 1/4 hours = 35 hours, 15 minutes
To calculate the total hours Vanessa worked last week, we need to subtract the time she took off from her typical work hours.
Vanessa typically works 8 hours per day for 5 days, which gives us a total of 40 hours (8 hours/day x 5 days/week).
Now, let's calculate the time she took off:
- On Tuesday, Vanessa took 90 minutes off, which is equivalent to 1 hour and 30 minutes.
- On Thursday, Vanessa took 45 minutes off, which is equivalent to 0 hours and 45 minutes.
- On Friday, Vanessa left 2 hours and 30 minutes early, which is equivalent to 2 hours and 30 minutes.
To find the total time Vanessa took off, we add up these time intervals:
1 hour and 30 minutes (Tuesday) + 0 hours and 45 minutes (Thursday) + 2 hours and 30 minutes (Friday) = 4 hours and 45 minutes.
Now, we subtract the time Vanessa took off from her typical work hours to find the total hours she worked:
40 hours - 4 hours and 45 minutes = 35 hours and 15 minutes.
So the correct answer is A. 35 hours 15 minutes.
