The number of minutes in 4000 seconds and round off to 1 significant figure is; 1 minutes

How to convert hours to seconds?

We are told that there are 3600 seconds in 1 hour.

Now, we want to find out the number of minutes in 4000 seconds and round off to 1 significant figure.

Thus;

If 3600 secs = 1 hour

Then 4000 secs = (4000 * 1)/3600 = 1.111 minutes

Approximating to 1 significant figure gives;

4000 secs = 1 minute
