1. A speed, found by dividing a distance measured in kilometers by a time measured in seconds.
True: rate = distance/time
30 mph = 60 miles/2 hours
2. You are given two pieces of information: (1) the price of gas in dollars per gallon and (2)the gas mileage of a car in miles per gallon. You are asked to find the cost of driving this car per mile. You should
a. divide the price of gas by the car's mileage
b. multipy the price of gas by the car's gas mileage
c. divide the car's gas mileage by the price of gas
[2.25 dollars/gallon]/[30 miles/gallon] = 0.075 (dollars/mile)
