Answer :
Sure! Let's break down the solution step-by-step:
1. Understand the Problem: We need to calculate how many houses a postal worker can deliver mail to in 1 hour, given that they can deliver to 18 houses in 15 minutes.
2. Determine Time Conversion:
- We know 1 hour is equal to 60 minutes.
3. Calculate the Number of 15-Minute Intervals in 1 Hour:
- Calculate how many 15-minute periods fit into 60 minutes.
- 60 minutes divided by 15 minutes per interval equals 4 intervals.
4. Calculate the Total Number of Houses Delivered in 1 Hour:
- If 18 houses can be delivered in one 15-minute interval, and there are 4 such intervals in 1 hour, we multiply 18 houses by 4 intervals.
- 18 houses × 4 intervals = 72 houses.
Therefore, the postal worker can deliver to 72 houses in 1 hour.
