Question: A bus leaves at 9:30. The ride takes 40 minutes and the walk home takes 12 minutes. What time do you arrive?
Let's think step by step.
- Total travel minutes = 40 + 12.
- 0 + 2 = 2 -> write 2
- 4 + 1 = 5 -> write 5
- written: 2 5 -> answer 52
- Leave at 9:30. Add 52 minutes: 30 + 52 = 82 minutes.
- 82 is more than 60, so subtract 60: 82 - 60 = 22, and add 1 hour: 9 + 1 = 10.
Answer: 10:22


Question: Dinner costs $68.45. You add a 10% tip and pay $90.00. How much change?
Let's think step by step.
- Bill is 6845 cents.
