Question 864058: I did a problem very similar to this one and I got it wrong. I really need help and I have to show all of my work!
On a 1287 mile long trip in windy conditions, a family calculates their fuel economy to be 18 miles per gallon over the 2 days it takes to reach their destination. On their 2-day return trip, with similar wind at their backs, their calculations show a fuel economy of 26 miles per gallon.
#1 Calculate the expected fuel economy of their vehicle in ideal (non-windy) conditions (f) as well as the influence of the wind (w) in miles per gallons.
#2Compare how many gallons of fuel they used for the round trip to the expected usage in idea (non-windy) travel conditions. Which uses more? By how many gallons? Round to the nearest hundredth, if necessary?
Thnaks for any help!!!!!!!!
