Write two equations for each scenario. One equation should be to compute the relative distance. The other should be to compute the total distance traveled for the same scenario using absolute value. Finally, given the information about the fuel economy, or the miles per gallon (mpg) for each car, calculate whether or not you have enough fuel for each trip. To do this, multiply the amount of fuel by the mpg to estimate the distance the car can travel with that much fuel. Scenario: a van will drive 10 miles north, 15 miles south, and then 5 miles north again. The van gets 33 miles per gallon, and there is in gallon of gas left in the tank. Compute the relative distance and the total distance. Then decide if there's enough fuel for the trip
