Wendy's Drive-Through Fast-food restaurants spend quite bit of time studying the amount of time cars spend in their drive throughs. Certainly, the faster the cars get through the drive- through, the more the opportunity for making money. QSR Magazine studied drive-through times for fast-food restaurants and found Wendy's in the drive-through of 138.5 seconds. Assuming drive-through times are normally distributed with a standard deviation of 29 seconds, answer the following. (a) What is the probability that a randomly selected car will get through Wendy's drive-through in less than 100 seconds? (b) What is the probability that a randomly selected car will spend more than 160 seconds in Wendy's drive-through? (c) What proportion of cars spend between 2 and 3 minutes in Wendy's drive-through? (d) Would it be unusual for a car to spend more than 3 minutes in Wendy's drive-through? Why? 41.

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
