A car travels at a speed of 80 km/h. Which of the following is correct to convert the speed of the car to hm/s?
(1 km = 10 hm, 1 h = 3600 s)

A. Divide 80 by 3600

B. Multiply 80 by 3600

C. Divide 80 by 10 and multiply the result obtained by 3600

D. Multiply 80 by 10 and divide the result obtained by 3600

Answer :

Answer: The correct answer is Option D.

Explanation:

We are given that car travels with a speed of 80 km/hr and we need to convert it into hm/s.

For that we use the conversions:

1 kilometer = 10 hectometer

And, 1 hour = 3600 seconds

To convert the quantity into hm/s, we multiply the numerator which is 80 by 10 to convert the whole quantity into hm/hr and now, to convert the result into hm/s finally, we divide the result by 3600.

[tex]\Rightarrow (\frac{80km1}{hr})(\frac{10hm}{1km})=\frac{80km}{hr}\\\\\Rightarrow (\frac{80km}{hr})(\frac{1hr}{3600s})=\frac{80hm}{3600s}[/tex]

Hence, the correct answer is option D.
