Respuesta :

Subtract the two numbers from largest to smallest:
4.43-4.12    (or because the hour is the same, you can leave the 4 out)
43-12=31
31 minutes

By walking from 4:12 pm to 4:43 pm, Joy's mom was able to walk for 31 minutes

Joy's mom walked from 4:12 pm to 4:43 pm.

To find out the number of minutes she walked, subtract the time she started walking from the time she stopped walking:

= Time stopped - Time started

= 4 :43 - 4:12

= 43 - 12 ⇒ isolate the minutes to make the subtraction easier

= 31 minutes

In conclusion, Joy's mom walked for 31 minutes.
