Question 1 Report
A car is travelling at an average speed of 80km/hr. Its speed in meters per second (m/s) is
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.
