60 miles per hour
distance=rate times time
first part
rate=60mph
time=3h
distance=60mph times 3h=180 miles
part 2
time=2 hours
rate=70mph
distance=70mph times 2h=140miles
total is 180mi+140mi=320miles

8 shifts.
Step-by-step explanation:
Brianna worked a total of 44 hours stacking shelves.
If she worked 
hour shifts,
How many shifts did she work?
