We will see that the car with the slowest rate is car d, with a rate of 66.7 mi/h, while the other cars have 75 mi/h.
Which car traveled at the slowest rate?
The rate at which the cars travel (also called the speed) is given by the quotient between the distance traveled and the time in which that distance was traveled.
Then, for each car we will the speeds:
- a) S = 300mi/4h = 75 mi/h
- b) S = 450mi/6h = 75 mi/h
- c) S = 750mi/10h = 75 mi/h
- d) S = 800mi/12h = 66.7 mi/h
Then we can see that the car with the smallest speed (or slowest rate) is car d, with a speed of 66.7 mi/h.
