Question

Harish runs faster than Ashok in a given length. To compare the Harish and Ashok in this fundamental physical quantities involved are: 

1) length only 

2) time only 

3) length and time 

4) neither length nor time

Answer 1

Correct option is 3) length and time 

To compare the running speeds of Harish and Ashok, we need to consider both length (the distance they run) and time (the duration it takes them to run that distance).
