Question

You are out shopping and lost track of time. It is 11:50, and you are supposed to pick up your dog at the vet by noon. You know it's going to take at least 20 minutes to get there.

Answer 1

Answer: 10 minutes

Step-by-step explanation:

Question wants to know the number of minutes you will be late by:

If you leave exactly at 11:50, and take 20 minutes to arrive, you will arrive at:

= 11:50 + 20 minutes

= 12:10

You were supposed to arrive by noon which is 12:00. You were therefore late by:

= 12:10 - 12:00

= 10 minutes
