Ellen recently purchased a new hybrid car and wants to check her gas mileage. At an odometer setting of 651.1 mi, she fills the tank. At 1314.4 mi, she requires 16.1 gal to re-fill the tank. Assuming that the tank is filled to the same level both times, how is the gas mileage best expressed?a) 40 mi/gal. b) 41 mi/gal.c) 41.2 mi/gal. d) 41.20 mi/gal.

Respuesta :

Answer:

d) 41.20 mi/gal.

Explanation:

Initial odometer reading, D1 = 651.1 mi

Final odometer reading, D2 = 1314.4 mi

Volume of gas used = 16.1 gal

Gas mileage = (D2 - D1)/V

= (1314.4 - 651.1)/16.1

= 41.2 mi/gal.
