A certain car traveled twice as many miles from Town A to Town B as it did from Town B to Town C. From Town A to Town B, the car averaged 25 miles per gallon, and from Town B to Town C, the car averaged 30 miles per gallon. What is the average miles per gallon that the car achieved on its trip from Town A through Town B to Town C? Choose one:  A) 24  B) 25  C) 23  D) 22  E) 26.5
step 1) took LCM of 25 and 30.. came as 150.   step 2) 150 distance between B to C... do 150/30 hence 5 gallons used   step 3) twice distance.. hence 150*2= 300... do as above.. 300/25= 12 gallons used   step 4) total gallons.. 5+12= 17 gallons   step ) total miles= 150+300=
