Colin drove 45 minutes to the air port. he arrived 90 minutes before his flight departed and then he spent 70 minutes in the air. once he landed colin spent 20 minutes gathering his language and the. he drive 35 minutes to his hotel what must be true of any expression that represents the hotel time collin spent traveling from his house to the hotel.

Given: The time taken to do each activity from Colin's house to his hotel in given.

To Find: what is true of any expression that represents the total time Collin spent traveling from his house to the hotel

Solution: Any expression will involve the sum of all the durations of his various activities i.e., 260 minutes or 4 hours and 20 minutes.

Explanation:

As each of the activities described is an independent activity that does not overlap, we can easily sum up the durations of each to find the total time Collin took from his house to the hotel.

We add it as follows :

he drove to the airport for 45 minutes + he waited at the airport for the flight to depart for 90 minutes + his fight duration was 70 minutes + upon landing, he gathered his luggage for 20 minutes + he drove to the hotel for 35 minutes.

So, 45+90+70+20+35 = 260 minutes

which means it took a total of 260 minutes or 4 hours and 20 minutes from Collin's house to his hotel.

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
