Guidelines for solving Exercise 4 on Page 28 of Math 5 Workbook
Problem Statement:
There are 9 cars transporting food into the city, with 5 leading cars carrying 36 tons each and 4 trailing cars carrying 45 tons each. What is the average amount of food each car transports?
Solution Method:
* Observations:
- The problem indicates:
+ 9 cars collectively transporting food into the city.
+ 5 leading cars, each carrying 36 tons.
+ 4 trailing cars, each carrying 45 tons.
- The problem requires: Calculate the average tons of food each car transports.
* Solution Approach:
- Step 1: Find the tons of food transported by the first 5 cars by multiplying the tons per car by 5.
- Step 2: Similarly, find the tons of food transported by the remaining 4 cars by multiplying the tons per car by 4.
- Step 3: Calculate the total tons of food transported by the 9 cars by adding the results from Step 1 and Step 2.
- Step 4: Find the average tons of food each car transports by dividing the total tons of food transported by the 9 cars (found in Step 3) by 9.
- Step 5: Convert the unit from tons to tons and conclude.
Answer:
The first 5 cars transport a total of 180 tons of food:
5 x 36 = 180 tons.
The remaining 4 cars transport a total of 180 tons of food:
4 x 45 = 180 tons.
The total food transported by the 9 cars is 360 tons.
The average tons of food each car transports is 40 tons, equivalent to 4 tons.
Answer: 4 tons.
