Expert Answer
Time - Time is an observed phenomenon, by means of which human beings sense and record changes in the environment and in the universe. Time has been called an illusion, a dimension, a smooth-flowing continuum, and an expression of separation among events that occur in the same physical location.
Now it depends, how and in what terms (units) you have to measure time.
SI unit of time is seconds.
Other units of time are minutes, hours etc.
1 h = 60 minutes = 60×60 = 3600 seconds
Devices which can be used to measure time are wall clock, watches etc. For accurate measurments, scientists have designed atomic clocks.
There are various formulae using which you can measure time.
For example,
if you have been provided with data say, speed of car and distance covered by it. Then using the given information you can substitute the values of speed and distance in the below formulae to find the value of time in which the distance was covered by the car.
