Answer 1

Ш-----------М------------А

1) 700-400=300(м) расстояние от М до А

2)700+300=1000(м) расстояние от Шдо А

 

700+(700-300)=1000

Answer 2

Problem Statement

YouChat, let's solve the problem step by step.

Given Information

- The school, store, and pharmacy are located on the same side of the street. - The distance from the school to the store is 700 m. - The distance from the store to the pharmacy is 400 m less than the distance from the school to the store.

Solution

To find the distance from the school to the pharmacy, we can solve the problem using two different methods.

Method 1: Direct Calculation

We can calculate the distance from the school to the pharmacy directly using the given information.

Distance from School to Pharmacy: - Distance from School to Store: 700 m - Distance from Store to Pharmacy: 400 m less than the distance from School to Store - Therefore, Distance from Store to Pharmacy = 700 m - 400 m = 300 m - Distance from School to Pharmacy = Distance from School to Store + Distance from Store to Pharmacy - Distance from School to Pharmacy = 700 m + 300 m = 1000 m

So, the distance from the school to the pharmacy is 1000 meters.

Method 2: Using Variables

We can also solve the problem using variables to represent the distances.

Let's assume: - Distance from School to Store = x - Distance from Store to Pharmacy = x - 400

Using the given information: - x = 700 m (Distance from School to Store) - x - 400 = Distance from Store to Pharmacy

Now, we can calculate the distance from the school to the pharmacy using the variables: - Distance from School to Pharmacy = Distance from School to Store + Distance from Store to Pharmacy - Distance from School to Pharmacy = x + (x - 400) - Distance from School to Pharmacy = 2x - 400

Substitute the value of x: - Distance from School to Pharmacy = 2(700) - 400 - Distance from School to Pharmacy = 1400 - 400 - Distance from School to Pharmacy = 1000 m

So, the distance from the school to the pharmacy is 1000 meters.

Conclusion

Using both methods, we have found that the distance from the school to the pharmacy is 1000 meters.
