Acceleration is a measure of the rate at which something can increase its speed. To calculate acceleration you use the formula f − s t where f is the final speed of the object, s is the starting speed of the object and t is the amount of time it took to change speeds. Three cars were measuring acceleration. Car A went from 20 miles per hour to 35 miles per hour in 5 seconds. Car B went from 10 miles per hour to 34 miles per hour in 3 seconds. Car C went from 0 miles per hour to 30 miles per hour in 6 seconds. Select the cars so they are in order from least to greatest acceleration.
