A relation is a set of inputs and outputs, often written as ordered pairs (input, output). We can also represent a relation as a mapping diagram or a graph. For example, the relation can be represented as:
Answer:
14.4 km = 1440000
Step-by-step explanation:
1 km = 1000m
14.4 km = 1000 ×14.4
=14400 m
1 m =100 cm
14400 m = 100 × 14400
= 1440000 cm
Answer:
x = 4200
Step-by-step explanation:
It is given 7 meters in 20 minutes.
We have to convert this ratio into "x" centimeters in 2 hours.
First, lets convert the given ratio to 2 hours (so time matches).
7 meters in 20 minutes
7 * 3 = 21 meters in 20 * 3 = 60 minutes (1 hr)
So,
21 meters in 1 hr
That would mean:
21 * 2 = 42 meters in 1 * 2 = 2 hours
Now, we have:
42 meters in 2 hours
The time is same, now we just need to convert 42 meters to centimeters.
<em>we know 100 cm = 1 meter, so</em>
<em>42 m * 100 = 4200 centimeters</em>
<em />
Thus,
x = 4200 (cm)
