To determine the best time for Denise's son to leave home to catch the bus and arrive at school by 9:00, we need to consider the bus schedule and the 5-minute walk to the bus stop.
1. Bus Schedule at 5th and Main:
- Arrival Time 1: 7:32
- Arrival Time 2: 8:24
- Arrival Time 3: 9:31
2. Since Denise's son needs to arrive at school by 9:00:
- The 9:31 bus won't work as it arrives at the stop after 9:00.
- The 7:32 bus arrives at Oak Hills Elementary at 7:53, which is too early.
- The 8:24 bus arrives at Oak Hills Elementary at 8:45, which is ideal.
3. Time to Leave Home:
- To catch the 8:24 bus, Denise's son needs to be at the bus stop by 8:24.
- Since it is a 5-minute walk to the bus stop, he needs to leave home by 8:19.
4. Given the options for the time to leave home:
- 7:25: Too early
- 8:05: Too early
- 8:15: Perfect timing
- 8:40: Too late
The best time for Denise's son to leave home to get to the bus stop is 8:15.
