Che-130 Pogil Activity Begin to Plan Your Solution 1. Restate the problem in your own words. Your statement should clearly identify what you need to find in order to solve the problem and provide an answer to the question. Using the information provided, is a far trip to a gas station with lower gas prices worth the trip? (Consider the different factors and monetary costs). 2. Identify the relevant information provided and any additional information that is needed. Driving distance to the cheap gas station is 8.7 km . Gas costs $3.51/gal next door, but $0.90/liter at the cheap station. You could earn $7.50/hour at your job instead of driving to get gas. It takes 3.5 minutes to fill your tank with gas. Your car can go 27.6 miles on one gallon of gasoline. You have just enough gas to drive to the cheap station, and your tank presently can hold an additional 15.6 gallons. The value of the gas currently in the tank is $3.51/gal.

Unformatted text preview: ⋅ You have to make a round trip. ⋅ Assume your average driving speed to and from the gas station is 45 mph. Average speed is equal to total distance traveled divided by the time it took to travel that distance. 3. Identify the concepts and relevant equations that are related to the problem. ⋅ Gallons to Liters: 1 US gallon = 3.7854118 liters ⋅ 1 liters = 0.264172051 US gallons ⋅ Miles to Kilometers: 1 miles = 1.609344 kilometers ⋅ 1 kilometer = 0.621371192 miles ⋅ 1 gallon of gasoline= 27.6 miles ⋅ Speed formula= Distance/Time 4. Identify how the concepts and relevant equations link the information to what you need to find. • Convert --$0.90/liter to $/gallons. 1 liters = 0.264172051 US gallons 0.264172051 liters x .90 = 0.237754846 gallons • Convert-- 8.7 km to miles 1 miles = 1.609344 kilometers 1 kilometer = 0.621371192 miles 8.7 km x 0.621371192 miles= 5.40592937miles...
