To know the distance, we need to know the rate of miles per dollars of gas.
We'll look for statements that give us this information, a Logical information.

(1) So we can calcultae # of gallons. But how much is the miles per gallon?
Insufficient.

(2) If we knew the gallons per dollar, this would be enough. As is, it is insufficient.
Insufficient.

Combined.
(1) gives gallons per dollar and (2) gives miles per gallon. Multiplying them by \$50 give our answer.
Sufficient

Statement 1 :

we can find out the total no. of gallons . 50/ 2.75= no. gallons. but we don't know how many miles we can go using per gallons. Not sufficient .

Statement 2 :

In this statement rate is given but we don't know the no. of gallons. Not sufficient.

Combining both statements:

we know no. of gallons + rate. Sufficient.
