Question 8 a car is traveling at a rate of 45 kilometers per hour. what is the car's rate in meters per second? how many meters will the car travel in 2 seconds? do not round your answers.

The rate in meters per second is 12.5

The car travel 25 meters in 2 seconds

Explanation:

For answering the question is necessary to know the following relations:

1. A kilometer is equivalent to 1000 meters

2. An hour is equivalent to 3600 seconds.

Then using the relations we first need to transform the kilometer per hour into meter per hour, as:

So, 45 Kilometers per hour is equivalent to 45000 meters per hour.

as a second step, we need to transform the meters per hour into meters per second, as:

So, 45 kilometers per hour is equivalent to 12.5meters per second.

That means that every second the car travel 12.5 meters. If the car travels 2 seconds, the meters that the car travel is equivalent to multiply 12.5 with 2, as:
