A vehicle is travelling 1.0x10^2 km/h. what is the spped of the vehicle in metres per second?

28m/s
27.8m/s
3.6x10^2m/s
1.0x10^4m/s

the value does not change when you multiply it by 1. So, write 1 in the ways you need to get the units you want:

100km/hr * 1000m/km * 1hr/3600s = 27.778 m/s

Well, the vehicle is definitely moving fast! If we want to convert from kilometers per hour to meters per second, we need to remember that 1 kilometer equals 1000 meters and 1 hour is equal to 3600 seconds. So, we can do a little math here: 1.0 x 10^2 km/h is equal to (1.0 x 10^2) x (1000/3600) m/s, which simplifies to approximately 27.8 m/s. So, the correct answer is 27.8 m/s.

To convert the speed from kilometers per hour to meters per second, you need to remember the conversion factor: 1 kilometer per hour is equal to 0.2778 meters per second.

So, to calculate the speed of the vehicle in meters per second, you can multiply the given speed of 1.0x10^2 km/h by the conversion factor:

1.0x10^2 km/h * 0.2778 m/s = 27.78 m/s

Therefore, the speed of the vehicle in meters per second is 27.78 m/s.

To convert the speed from kilometers per hour (km/h) to meters per second (m/s), you need to multiply the speed in km/h by a conversion factor.

The conversion factor is 1 km = 1000 m and 1 hour = 3600 seconds.

Let's break it down step by step:

Given:
Speed = 1.0 x 10^2 km/h

Step 1: Convert kilometers to meters
1 km = 1000 m
So, 1.0 x 10^2 km = 1.0 x 10^2 * 1000 m = 1.0 x 10^5 m

Step 2: Convert hours to seconds
1 hour = 3600 seconds
So, 1.0 x 10^2 km/h = 1.0 x 10^5 m/3600 s = 1.0 x 10^5 / 3600 m/s

Step 3: Simplify the result
1.0 x 10^5 / 3600 m/s can be written as 1.0 x 10^5 m/3600 s

Now, let's calculate the result:

1.0 x 10^5 m / 3600 s = 27.8 m/s (approximately)

Therefore, the speed of the vehicle in meters per second is approximately 27.8 m/s.

So, the correct answer is:
27.8 m/s
