Which situation is best represented using a negative integer? a deposit of $35 into a bank account the temperature decreasing by 18º an additional 5 gallons of gas being put into a car a student reading today for 20 minutes longer than yesterday

A temperature decrease by 18° because it's a decrease, which means to lessen, which could be possible to get into the negatives.

The answer is B. This is the only situation that can have a negative logically. With A you can't have negative dollars. With C you can't have negative gallons of gas. And with d you can't have negative pages read. 

The first one is correct

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
