Right answer would get all the points! Thank you!

How much fuel is burned by Nova Mn College Students for the Thanksgiving visit home? A survey of 40 Randome student reveals the following: ( I have already measured the distance)

- 12 come from Rockpile ( 34 mile to school)

- 8 come from DC (32 mile to school)

- 6 come from Vienna, ( 16.3 mile to school)

- 4 come from Frederick ( 46.3 mile to school)

Assume that average car has 1.5 ( half have two occupants and half have one occupant). The student population is 10,500 students. Average fuel economy is 30 mil/gal.

Explanation / Answer

Avg distance that 40 students travel=12*34+8*30.3+6*16.3+4*46.3 =933.4 miles

Avg distance covered by 3 dstudents or 2 cars =933.4/40 *3 =70.005 miles

Total number of cars needed =10500*2/3 =7000 cars

Avg distance covered by 7000 cars =7000/2 *70.005 =245017.5 miles

Avg mileage =30 miles/gallon

For 245017.5 miles =245017.5/30 =8167.25 gallons (ans)
