Sheldon can either take a train or an airplane to San Francisco. If the train takes 8 hours and 5 minutes and the plane takes 1 hours and 41 minutes, how much time would he save taking an airplane?


To find out how much time Sheldon would save by taking the airplane instead of the train, we need to compare the durations of both trips.

### Step 1: Convert the time durations into minutes.

- **Train time**: \( 8 \) hours and \( 5 \) minutes
  - Convert hours to minutes: \( 8 \times 60 = 480 \) minutes
  - Add the extra minutes: \( 480 + 5 = 485 \) minutes

- **Airplane time**: \( 1 \) hour and \( 41 \) minutes
  - Convert hours to minutes: \( 1 \times 60 = 60 \) minutes
  - Add the extra minutes: \( 60 + 41 = 101 \) minutes

### Step 2: Subtract the airplane time from the train time.

\[
485 \text{ minutes} - 101 \text{ minutes} = 384 \text{ minutes}
\]

### Step 3: Convert the time saved back into hours and minutes.

- \( 384 \) minutes is equal to \( 6 \) hours and \( 24 \) minutes.

So, Sheldon would save **6 hours and 24 minutes** by taking the airplane instead of the train.

Would you like further details or have any questions about the solution? Here are five related questions to consider:

1. What would be the time saved if the train took an extra 15 minutes due to a delay?
2. How much time would Sheldon save per hour of the train journey by taking the airplane?
3. If the airplane was delayed by 30 minutes, what would the new time saved be?
4. How long would the trip take if Sheldon had to take both the train and airplane?
5. What is the total percentage reduction in travel time by choosing the airplane over the train?

**Tip**: Breaking down the problem into smaller parts, like converting hours into minutes, helps simplify the calculations and avoids errors.
