Guidance for solving problem 3 on page 133 of Math 5 textbook

Problem:
A person leaves point A at 6:45 AM and arrives at point B at 8:30 AM. During the journey, the person takes a 15-minute break. Excluding this break time, how much time does the person take to travel from point A to point B?

Solution Method:
- Given:
+ Departure from A: 6:45 AM
+ Arrival at B: 8:30 AM
+ Midway stop: 15 minutes
- Requirement: Calculate the time taken to travel from A to B (excluding rest time).
- Approach: To find the time taken for the person to travel from A to B, subtract the departure time from the arrival time, then subtract the midway break time.

Answer:
The time taken for the person to travel from A to B (excluding rest time) is:
(8:30 AM - 6:45 AM) - 15 minutes = 1 hour 30 minutes
Answer: 1 hour 30 minutes.

Frequently Asked Questions

What is the time taken to travel from point A to point B excluding breaks?

The total travel time from point A to point B, not including the 15-minute break, is 1 hour and 30 minutes. This is calculated by subtracting the departure time of 6:45 AM from the arrival time of 8:30 AM and then deducting the break.

How do you calculate travel time without including rest periods?

To calculate travel time without including rest periods, first determine the total time from departure to arrival. Then, subtract any breaks taken during the journey. This method ensures you accurately reflect only the active travel time.

What specific steps are involved in solving exercise 3 on page 133?

Solving exercise 3 involves several steps: identify departure and arrival times, calculate the total travel duration, and subtract any break time. For this exercise, you start with 6:45 AM and 8:30 AM, then subtract the 15-minute break to find the actual travel time.

Can you explain the method used to solve this travel problem?

Certainly! The method involves calculating the difference between the arrival and departure times, which gives you the total time. Then, subtract the break time to determine the net travel duration. This systematic approach provides clarity in problem-solving.
