Question
Write an equality that represents the following scenario
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
20t + 3 < or equal to 60
20t +3 > or equal to 60
20t-3 < or equal to 60
20 t + 3 < 60

To represent the scenario mathematically, we need to account for the total time taken by Katlyn, which includes both the time for the trip to the supermarket and back as well as the additional time spent preparing.
Let \( t \) be the number of trips Katlyn makes to the supermarket and back. According to the information provided:
1. The walking time for a round trip to the supermarket is 20 minutes.
2. She spends an additional 3 minutes (1 minute to tie her shoes and 2 minutes to check the route) each time she makes a trip.
The total time for \( t \) trips is thus given by the equation:
\[ 20t + 3t = 20t + 3 \]
We want to find out how many trips she can complete in no more than 60 minutes, so we set up the inequality:
\[ 20t + 3 \leq 60 \]
This corresponds to the following expression from your options:
- \( 20t + 3 \leq 60 \)
Thus, the correct answer is:
\[ 20t + 3 \leq 60 \]
