percentage- A-B/total×100

and 1 hour=60minute

Sᴛᴇᴘꜱ

as we know that Anil usually takes 2 hours to reach his office

1 hour =60 minutes

so 2 hours=120 minutes

so if he started late by 30 minutes then his speed that should be increased to go at the same time can be found by finding it's percentage

so 30/120×100

=25%
