Answer:

12:07 or 7 minutes into midday

Step-by-step explanation:

You have to find the Least/lowest common multiple (LCM) of 60 and 70 which  is 420.

So you divide 420 by 60 (60 second in a minute) which gives you the answer

7. So if you add 7 minutes into midday/add 7 minutes into 12:00,

it gives you the answer

<u><em>12:07 or 7 minutes into midday</em></u>
