Acar 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

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.

Hence, the correct answer is option D.
