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.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
