The traffic engineer for a large city is conducting a study on traffic flow at a certain intersection near the city administration building. The engineer will collect data on different variables related to the intersection each day for ten days. Of the following variables, which will be measured using continuous data

Options

A. The number of cars passing through the intersection in one hour

B. The number of pedestrians crossing the intersection in one hour

C. The number of bicyclists crossing the intersection in one hour

D. The number of food trucks that park within four blocks of the intersection

E. The number of minutes for a car to get from the intersection to the administration building

The number of minutes for a car to get from the intersection to the administration building

Step-by-step explanation:

A variable is said to be discrete if and only if it has a countable number of values. While a variable is said to be continuous if it can take infinitely many values.

Option a to d contains discrete variables (1 hour) and (4 blocks), so they can't be regarded as the right option. 1 hour and 4 blocks are specified values and they can't take any other fraction of values aside 1 and 4 respectively.

Looking at option e, the variable, number of minute as stated in this option is a continuous variable. This is so because at any two interval of minutes, fractions and lots of a minute can always be recorded by the engineer to study the traffic flow
