Answer:
The local train's journey time is 1.3 times as long as the journey time of the express train.
Step-by-step explanation:
Given that:
Travelling time of express train = 2 hours and 45 minutes
We will convert this time into minutes
Travelling time of express train = 2*60 + 45 = 120+45 = 165 minutes
Travelling time of local train = 3 hours and 40 minutes = 220 minutes
Let,
n be the number of times.
Local train travelling time = Number of times * Express train travelling time
220 = n * 165
Dividing both sides by 165
Hence,
The local train's journey time is 1.3 times as long as the journey time of the express train.

In other to draw a mapping diagram for the ordered pairs (1,0) (3,0) (5,4) (7,4) (9,4).
We identify the domain and range:
The domain is the set of the first coordinates of the ordered pairs.
Domain={1,3,5,7,9}
The range is the set of all the second coordinates.
Range: {0,4}

In situations like this, ALWAYS (!) make as sketch.
Divide the areas by adding dotted lines on sensible places, and write in the missing numbers for the correct distances.
The only possible difficult one is the triangle, which is the half of a rectangle. So you are dealing with a series of areas of rectangles. That is really easy if you understand what you are doing.
Total area =
area 1 + area 2 + area 3 + area 4
10*4 + 4*7 + 3*13 + (0.5 * 7*17)
40 + 28 + 42 + 59.5
Total area = 169.5 yd²
