A car travels 60 m in 3 s. What is its average speed?

Average speed is the total distance traveled divided by the total time taken. Here the car covers 60 m in 3 s, so the average speed is 60 ÷ 3 = 20 m/s. This is the correct result because it directly uses the definition of average speed. The other values would require different times for the same distance (for example, 10 m/s would mean 60 m in 6 s, 30 m/s would mean 60 m in 2 s, and 60 m/s would mean 60 m in 1 s), but with the given numbers the calculation gives 20 m/s.
