# Science/Math Question? Please help...thanks!?

The Toyota RAV4 EV (1997-2003) was one of the earlier all-electric vehicles. Its nickel-metal hydride battery pack could store 27 kWh; its average range was 100 miles.

a) How much did it cost to operate, per mile, with electricity costing 9¢/kWh?

b) The non-EV RAV4 got 28 mpg. With gasoline at \$4.00/gal, what was its operation cost?

c) What is the quoted “mpg” that the RAV4 EV obtained—the mileage equivalent to a standard SUV?

a.) 27/100 = .27kWh per mi.

then

.27kWh x \$.09 = \$.0243 per mi.

b.)\$4.00/28 = \$.1429 per mi.

c.)\$4.00/.0243 = 164.6091 mpg equivalent

comments.

a.) can be in simpler form 27 x .09 / 100 = .0243

c.) in English is just ask how far can i go on 4 bucks if one mile costs 2.4 cents?

Get the real answers by asking others who own one.   It is not so easy to figure out mathematically....because batteries do not fill up simply like a gas tank.  Batteries also deteriorate(age) so that needs replacing every so often (I don't know the life of a ni-cad battery and you got to find that out stuff. Asking other owners would be the best way to find out "real world" picture.
