anonymous · Answer

I got 5.3 for A and 6.42 for B.

phi · Answer

when you read (a), it asks for "hours ... per dollar"
you see x per y
that means write  $$ \frac{x}{y} $$
so find the number of hours and divide by the number of dollars
to get a fraction
can you do that ?

anonymous · Answer

Is A 5.3 and B 6.42?

phi · Answer

number of hours and divide by the number of dollars

anonymous · Answer

So 3 / 16 ?

phi · Answer

yes, but it looks like they want a decimal rounded to the nearest 100th

anonymous · Answer

So the answer for A would be 0.1875 but rounded to nearest 100th would be 0.19?

phi · Answer

yes  0.19

for (b) they want "minutes .... per mile"
so
77 minutes /12 miles = 6.41666...  
rounded   6.42 minutes per mile
