Answer:
28.57% probability that the speed of a car is between 17 and 23 mph
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X between c and d is given by the following formula:

14 to 35 mph and is uniformly distributed.
This means that 
What is the probability that the speed of a car is between 17 and 23 mph?
