Answer 2

The speed of the car in m/s and km/minute units are, 30m/s and 1.8 km/minute respectively.

Given : The speed of a car 108km/h.

To find : The speed of the car in m/s and km/minute units.

Solution :

We can simply solve this numerical problem by using the following process. (our goal is to convert the unit of the speed of the car)

Now, we know that :

• 1 kilometre = 1000 metres
• 1 hour = 3600 seconds
• 1 hour = 60 minutes

By using the above mentioned unit conversion references, we get :

The car goes in 1 hour = 108 km

The car goes in 3600 seconds = (108 × 1000) m

The car goes in 1 second = 108000/3600 = 30m

So, Speed of the car in m/s unit = 30 m/s

Similarly,

The car goes in 1 hour = 108 km

The car goes in 60 minutes = 108 km

The car goes in 1 minute = 108/60 = 1.8 km

So, Speed of the car in km/minute unit = 1.8 km/minute

Hence, the speed of the car in m/s and km/minute units are, 30m/s and 1.8 km/minute respectively.
