The unit rate of the car A is 30 miles per hour and the unit rate of the car B is 30.3 miles per hour.
<h3>What is the unit rate of each car?</h3>
In this question we find two case of two car travelling at constant speed, meaning that traveled distance (x), in miles, is directly proportional to time (t), in hours, then the unit rate of each car (v), in miles per hour, is represented by the following formula:
v = x / t (1)
Now we proceed to determine the unit rate of each case:
Car A - x = 45 / 2 miles, t = 3 / 4 hours
v = (45 / 2 mi) / (3 / 4 h)
v = 30 mi / h
Car B - x = 101 / 4 miles, t = 5 / 6 hours
v = (101 / 4 mi) / (5 / 6 h)
v = 30.3 mi / h
The unit rate of the car A is 30 miles per hour and the unit rate of the car B is 30.3 miles per hour.
