Question

A car is driving at 55 kilometers per hour. How far, in meters, does it travel in 2 seconds?

Answer 1

It will travel 30.5556          

First find the speed in metre per second.

then multiply it by 2                                                                                                                    

Answer 2

Answer

Find out the how far, in meters, does it travel in 2 seconds .

To prove

Let us assume that distance travel in 2 seconds be x.

Formula

$Speed = \frac{Distance}{Time}$

As given

A car is driving at 55 kilometers per hour.

Now convert kilometer per hour into meter per second.

As 1 kilometer = 1000 meter

     1 hour = 3600 second

$\frac{55\ kilometer}{hour} = \frac{55\times 1000\meter}{3600\second}$

thus

$Speed = \frac{550}{36} meter\ per\ second$

Time = 2 second

Put in the above formula.

$\frac{550}{36} = \frac{x}{2}$

$x = \frac{2\times 550}{36}$

$x = \frac{1100}{36}$

x = 30.56 meter (approx)

Therefore distance traveled in 2 second be  30.56 meter (approx) .
