A car travels 120 m in 6 s along a straight road. What is its average speed?

Explanation:
Average speed is the total distance traveled divided by the total time taken. For this car, that’s 120 meters in 6 seconds, so the average speed is 120 ÷ 6 = 20 meters per second. This value in m/s is the correct rate of motion for the given scenario. If you compare other possibilities, they would imply different distances in the same 6 seconds: 15 m/s would make 90 meters, 24 m/s would make 144 meters, and 6 m/s would make 36 meters, none of which match the 120 m stated.
