Question 880472: i travel 90km to and from work and i have a 15.4 gallon fuel tank how many days can i go without filling up?. vehicle can go 22 mpg city and 30 mpg highway Answer by josgarithmetic(39620) (Show Source):
Change the kilometer distance into miles.
5280 feet = 1 mile
1 foot = 12 inches
1 inch = 2.54 cm
100 cm = 1 m
1000 m = 1 km
Let n = number of days.
Let d = 90 kilometers, the one way distance.
2nd = the distance to be traveled on 15.4 gallons of fuel.
v=15.4 gallons of fuel
You have two fuel efficiency rates and are not given how the trip is distributed.
- ;
Make the needed conversion for d and then solve the inequality for d.
