### SAT Prep Class: Solving Simple Ratio Problems

Check out Bas Rutten's Liver Shot on MMA Surge: http://bit.ly/MMASurgeEp1 SAT Prep Question #17 Question: If a car travels 30 mph, how far does it travel in 1 minute?? This problem can be solved by turning it into a ratio by using the information you already have. It's important to write down the information provided and follow it through step by step to find the number you need.? Solve the Problem 1. Because the car is traveling at 30 mph, you know that it goes 30 miles in one hour. Write this down as a ratio:? 30 miles 1 hour 2. Since you need to find the time in minutes instead of hours, convert the hours into minutes.? 1 hour = 60 minutes, so:? 30 miles 60 minutes 3. Now you can simplify your ratio:? 30?= ?1 mile 60 ? ? 2 minutes So now you know that the car travels 1 mile every 2 minutes.? 4. Since you want to find the distance traveled in one minute instead of 2 minutes, reduce the ratio further by dividing the time and distance by 2.? 1 mile? ? ? ? = ??1/2 mile 2 minutes ? ? ?1 minute The car travels 1/2 mile in 1 minute.
