why switch to decimals, and end up with an approximate answer?
Use fractions and get an exact answer.

1km/30s = 2km/min = 120 km/hr

To calculate the speed of the vehicle in km/h, we first need to convert the distance from meters to kilometers.

1000m = 1km

Now, we need to calculate the speed of the vehicle:

Speed = Distance / Time

Speed = 1 km / 30 seconds = 0.0333 km/s

Now, we need to convert this speed from km/s to km/h:

1 hour = 3600 seconds

Speed = 0.0333 km/s x 3600 s/h = 119.88 km/h

Therefore, the speed of the vehicle was approximately 119.88 km/h.

You are correct. I apologize for the oversight.

1 km / 30 seconds can be simplified by converting seconds to minutes:

1 km / 30 seconds = 2 km / 60 seconds = 2 km/minute

Since there are 60 minutes in an hour, it means:

2 km/minute x 60 minutes/hour = 120 km/h

Therefore, the speed of the vehicle was exactly 120 km/h. Thank you for pointing that out.
