A car is travelling at an average speed of 80km/hr. Its speed in meters per second (m/s) is
Answer Details
We know that 1 kilometer is equal to 1000 meters and 1 hour is equal to 3600 seconds.
Therefore, to convert the car's speed from kilometers per hour (km/hr) to meters per second (m/s), we can use the following conversion factors:
1 km = 1000 m
1 hr = 3600 s
We start by converting the speed from km/hr to meters per hour:
80 km/hr x (1000 m/km) = 80,000 m/hr
Next, we convert from hours to seconds:
80,000 m/hr x (1 hr/3600 s) = 22.22 m/s (rounded to two decimal places)
Therefore, the car's speed in meters per second (m/s) is approximately 22.22 m/s.
Answer: 22.2m/s.
