It takes bruce 12 h to complete his training. it takes oliver approximately 2 days, 2 h, and 15 min to complete
his training how many hours does it take oliver to complete his training show work using correct conversion factors

Oliver completed his training work in 50.25 hours

Step-by-step explanation:

we know that

1 day= 24 hours

1 hour=60 minutes

we have

2 days, 2 h, and 15 min

Convert days to hours

2 days=2(24)=48 hours

Convert minutes to hour

15 min=15(1/60)=1/4=0.25 h

so

2 days, 2 h, and 15 min=(48)+(2)+(0.25)=50.25 h

therefore

Oliver completed his training work in 50.25 hours

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
