How to Convert Speed from Kilometers per Hour to Hectometers per Second?

What is the correct method to convert the speed of a car from kilometers per hour to hectometers per second?

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:

The correct answer is Option D.

To convert the speed of a car from kilometers per hour to hectometers per second, we need to utilize the given conversion factors: 1 kilometer = 10 hectometers and 1 hour = 3600 seconds.

Firstly, we multiply the speed of the car (80 km/h) by 10 to convert it to hectometers per hour. This gives us 800 hm/hr.

Next, to convert the speed to hectometers per second, we need to divide the result obtained by 3600 (the number of seconds in an hour).

Therefore, the correct method is to multiply 80 by 10 and then divide the result obtained by 3600, resulting in the speed of the car in hectometers per second.
