Step-by-step guide to solving Exercise 3 Page 58 Math 5

Problem:
A person rides a bicycle, covering 10.8km per hour for the first 3 hours and 9.52km per hour for the next 4 hours. Question: How many kilometers does the person travel?

Solution Method:
* Problem Summary:
First 3 hours: Travelled 10.8 km/ 1 hour
Next 4 hours: Travelled 9.52 km/ 1 hour
Distance travelled by the person: ? km
* Solution Steps:
- Step 1: Calculate the distance travelled in the first 3 hours by multiplying the speed by the time.
- Step 2: Calculate the distance travelled in the next 4 hours by multiplying the speed by the time.
- Step 3: Calculate the total distance travelled by adding the distances from steps 1 and 2.

Answer:
The distance travelled by the person in the first 3 hours is:
10.8 x 3 = 32.4 (km)
The distance travelled by the person in the next 4 hours is:
9.52 x 4 = 38.08 (km)
The total distance travelled by the person is:
32.4 + 38.08 = 70.48 (km)
Final Answer: 70.48km.

Frequently Asked Questions

What is the total distance traveled by a person riding a bicycle?

The total distance traveled by the person riding the bicycle is 70.48 kilometers. This includes 32.4 kilometers covered in the first 3 hours at a speed of 10.8 km/h and 38.08 kilometers covered in the next 4 hours at a speed of 9.52 km/h.

How do you calculate the distance traveled in each segment of the ride?

To calculate the distance traveled in each segment, multiply the speed by the time. For the first 3 hours at 10.8 km/h, the calculation is 10.8 km/h multiplied by 3 hours, which equals 32.4 km. For the next 4 hours at 9.52 km/h, the calculation is 9.52 km/h multiplied by 4 hours, which equals 38.08 km.

What steps are involved in solving Exercise 3 from the Math 5 textbook?

Solving Exercise 3 involves three key steps: First, calculate the distance for the initial 3 hours by multiplying the speed of 10.8 km/h by the time. Second, calculate the distance for the next 4 hours at 9.52 km/h. Finally, sum the distances from both segments to find the total distance traveled.

Why is it important to break down the problem into smaller parts?

Breaking down the problem into smaller parts simplifies the calculation process and enhances understanding. It allows for a clearer view of each segment's contribution to the total distance, ensuring accuracy in the final answer.
