Katlyn takes 20 minutes to walk from her house to the supermarket and back. After stepping outside her house, she takes 1 minute to tie her shoes and 2 minutes to check the route on her phone. How many trips can she take to the supermarket and back in 60 minutes? 1. 20t + 3 < 60 2. 20t - ≤ 60 3. 20t + 3 ≤ 60 4. 20t + 3 ≥ 60
The correct inequality to represent this situation is:
20t + 3 < 60, since she takes 20 minutes for each trip and adds 3 minutes for tying her shoes and checking the route.
